Answer:
The program in C is as follows:
#include <stdio.h>
char turn_to_letter(double score){
char lettergrade = 'A';
if(score>=80){ lettergrade = 'A'; }
else if(score>=70){ lettergrade = 'B'; }
else if(score>=60){ lettergrade = 'C'; }
else if(score>=50){ lettergrade = 'D'; }
else{lettergrade = 'F';}
return lettergrade;
}
int main(){
int midterm, final;
double score;
printf("Midterm: "); scanf("%d", &midterm);
printf("Final: "); scanf("%d", &final);
score = 0.4 * midterm + 0.6 * final;
printf("Score: %lf\n", score);
printf("Letter Grade: %c",turn_to_letter(score));
return 0;
}
Explanation:
The function begins here
char turn_to_letter(double score){
This initializes lettergrade to A
char lettergrade = 'A';
For scores above or equal to 80, grade is A
if(score>=80){ lettergrade = 'A'; }
For scores above or equal to 70, grade is B
else if(score>=70){ lettergrade = 'B'; }
For scores above or equal to 60, grade is C
else if(score>=60){ lettergrade = 'C'; }
For scores above or equal to 50, grade is D
else if(score>=50){ lettergrade = 'D'; }
Grade is F for other scores
else{lettergrade = 'F';}
This returns the letter grade
return lettergrade;
}
The main begins here
int main(){
This declares the midterm and final scores as integer
int midterm, final;
This declares the total score as double
double score;
These get input for midterm score
printf("Midterm: "); scanf("%d", &midterm);
These get input for final score
printf("Final: "); scanf("%d", &final);
This calculates the total score
score = 0.4 * midterm + 0.6 * final;
This prints the calculated total score
printf("Score: %lf\n", score);
This calls the turn_to_letter function and prints the returned letter grade
printf("Letter Grade: %c",turn_to_letter(score));
return 0;
}

Answer:
11001100 = 204
11111111 = 255
Explanation:
For 11001100:
1*2⁷ + 1*2⁶ + 0*2⁵ + 0*2⁴ + 1*2³ + 1*2² + 0*2¹ + 0*2⁰ = 204
Just replace 1's by 0's in the following calculation to do it for every 8 bit number:
1*2⁷ + 1*2⁶ + 1*2⁵ + 1*2⁴ + 1*2³ + 1*2² + 1*2¹ + 1*2⁰ = 255
If you don't want to do the calculation yourself, you can set the windows calculator in programmer mode, then select binary and key in the number.

This program exercise #4 wants the user to write a program in python that contains a list of movies titles, years and movie rating. You will need to display a menu option that allows the user to list all of the movies, add a movie, delete a movie and exit out of the program. This will be done using lists and the functions to add an element to a list and how to delete an element to a list. The program should be written utilizing functions in python for the main function, the display_menu function, the delete function, the add function and the list movie function. You can place this all in one python file or include them in various python files that include them into the main program. Let me know if you have any questions with this exercise. Output Screen: COMMAND MENU list - List all movies add - Add a movie del - Delete a movie exit - Exit program Command List: list 1. Monty Python and the Holy Grail, 1979, R 2. On the Waterfront, 1954, PG 3. Cat on a Hot Tim Roof, 1958, R Command: add Name: Gone with the Wind Year: 1939 Rating: PG Gone with the Wind was added.

Create a public class named InsertionSorter. It should provide one class method sort. sort accepts an array of Comparables and sorts them in ascending order. You should sort the array in place, meaning that you modify the original array, and return the number of swaps required to sort the array as an int. That's how we'll know that you've correctly implemented insertion sort. If the array is null you should throw an IllegalArgumentException. You can assume that the array does not contain any null values.
To receive credit implement insertion sort as follows. Have the sorted part start at the left and grow to the right. Each step takes the left-most value from the unsorted part of the array and move it leftward, swapping elements until it is in the correct place. Do not swap equal values. This will make your sort unstable and cause you to fail the test suites.
Answer:
Explanation:
The following code is written in Java it uses an insertion sort algorithm to sort a Comparable array that is passed as an input. The method itseld returns the number of changes that need to be made in order to fully sort the array.
class InsertionSorter {
private static Object IllegalArgumentException;
public static void main(String[] args) throws Throwable {
Comparable[] myarr = {1, 6, 15, 2, 5, 3, 8, 33, 10};
System.out.println(insertionSort(myarr));
}
public static int insertionSort(Comparable[] array) throws Throwable {
try {
int i, j;
Comparable newValue;
int count = 0;
for (i = 1; i < array.length; i++) {
newValue = array[i];
j = i;
while (j > 0 && (array[j - 1].compareTo(newValue)>0)) {
array[j] = array[j - 1];
j--;
count += 1;
}
array[j] = newValue;
}
return count;
} catch (Exception e) {
throw (Throwable) IllegalArgumentException;
}
}

2.1 A friend is interested in installing a wireless LAN in her small business. She has about a dozen employees. You are setting up an 802.11g wireless access point for her business. Your aggregate throughput is only about 6 Mbps. List at least two possible reasons for this low throughput.
Answer:
The two reasons for low throughput are as follows:
1-Low throughput is due to the fall of throughput is more with distance from the source.
2-The throughput is shared by multiple hosts and they are all using at the same time.
Explanation:
As the aggregate throughput of the 802.11g wireless access point is same, thus when you go farther from it or the number of uses increases, the overall value of individual throughput decreases.
C++ coding, help
In this program you will be reading numbers from a file. You will validate the numbers and calculate the average of all of the valid numbers.
Your program will read in a file with numbers. The numbers will be of type double.
The numbers should be in the range from 0 to 110 (inclusive). You need to count all of the numbers between 0 and 110. You also need to calculate the average of these numbers.
If a number is not valid (that is, it is less than 0 or greater than 110) you need to count it (as a count of invalid values) and you need to write out the number to a file called "invalid-numbers.txt". Values written to file invalid-numbers.txt should be in fixed format with two digits to the right of the decimal point.
As you did in lab lesson 7 part 1 you need to read in the input file name using cin.
The output from your program will be written to cout. The output must contain the file being processed, the total number of values read in from the file, the number of invalid values read in, the number of valid values read in.
The last thing you need to output is either the average of the valid values or an error message. The average must have two digits of precision to the right of the decimal point and must be in fixed format. If there is not valid average you should output the message:
An average cannot be calculated
In what case would you display this message?
If the input file cannot be opened, you will need to output a message. Assume the input file name is badinput.txt and it cannot be opened. You will display the following error message to cout
File "badinput.txt" could not be opened
Here is an example of a working program:
Assume the file name read in from cin is:
input.txt
and that input.txt contains:
-12
0
98.5
100
105.5
93.5
88
75
-3
111
89
-12
Your program would output the following:
Reading from file "input.txt"
Total values: 12
Invalid values: 4
Valid values: 8
Average of valid values: 81.19
The contents written out to file invalid-numbers.txt are:
-12
-3
111
-12
You are reading from an input file and you are writing to an output file. Make sure you close both files after you are finished using them. You must do this in your program, you cannot just let the operating system close the files for you.
For tests where there is output written to an output file the contents of the output file will determine if you passed that test or not. For cases where you have written out to cout the tests will check the output sent to cout. In some cases output will be written to a file and to cout. When this is the case the test will be run twice with the same input. Once to test cout and once to test the contents of the output file. An example of this would be tests 2 and 3. Both use the same input file. Test 2 check the output written to cout and test 3 checks the output written to the file invalid-numbers.txt.
Answer:
The program in C++ is as follows:
#include <fstream>
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
string filename;
cout<<"Filename: ";
cin>>filename;
ifstream inFile(filename);
if(!inFile) {
cout << endl << "Cannot open file " << filename;
return 1; }
ofstream fout;
ifstream fin;
fin.open("invalid-numbers.txt");
fout.open ("invalid-numbers.txt",ios::app);
double sum = 0; int valid = 0; int invalid = 0;
double num = 0;
while(!inFile.eof()) {
inFile >> num;
if(num >= 0 && num<=110){ sum+=num; valid++; }
else{ invalid++;
if(fin.is_open()){
fout<<fixed<<setprecision(2)<<num<<"\n"; } } }
fin.close();
fout.close();
inFile.close();
cout<<"Total values: "<<valid+invalid<<endl;
cout<<"Invalid values: "<<invalid<<endl;
cout<<"Valid values: "<<valid<<endl;
cout<<"Average of valid values: "<<fixed<<setprecision(2)<<sum/valid<<endl;
double inv;
ifstream inFiles("invalid-numbers.txt");
while(!inFiles.eof()) {
inFiles >> inv;
cout<<inv<<"\n";
}
inFiles.close();
return 0;
}

LAB: Contact list A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name. Assume that the list will always contain less than 20 word pairs. Ex: If the input is: 3 Joe 123-5432 Linda 983-4123 Frank 867-5309 Frank the output is: 867-5309
Answer:
The program in Python is as follows:
n = int(input(""))
numList = []
for i in range(n):
word_pair = input("")
numList.append(word_pair)
name = input("")
for i in range(n):
if name.lower() in numList[i].lower():
phone = numList[i].split(" ")
print(phone[1])
Explanation:
This gets the number of the list, n
n = int(input(""))
This initializes list
numList = []
This iterates through n
for i in range(n):
This gets each word pair
word_pair = input("")
This appends each word pair to the list
numList.append(word_pair)
This gets a name to search from the user
name = input("")
This iterates through n
for i in range(n):
If the name exists in the list
if name.lower() in numList[i].lower():
This gets the phone number associated to that name
phone = numList[i].split(" ")
This prints the phone number
print(phone[1])

Object Oriented Programming (OOPS or OOPS for Object Oriented Programming System) is the most widely used programming paradigm today. While most of the popular programming languages are multi-paradigm, the support to object-oriented programming is fundamental for large projects. Of course OOP has its share of critics. Nowadays functional programming seems the new trendy approach. Still, criticism is due mostly to misuse of OOP.

To reduce the number of used digital outputs of the microcontroller, the display board is connected to the main board through the integrated circuit of the decoder, which converts binary coded decimal (BCD) values to signals for the seven-segment display. So, to show any number on the display you need to set the required BCD code on the microcontroller's outputs. Write a program to convert an integer number represented as a string to a BCD code required for the display. In the BCD code, every decimal digit is encoded with its four-bit binary value. Encoding all digits of the decimal number and concatenating the resulting codes into one string you will get a resulting BCD code. A space is used to separate digits in the BCD code and make it more readable. For example, a number 173 will be encoded to BCD as 0001 0111 0011.
Answer:
The program in Python is as follows:
BCD = ["0001","0010","0011","0100","0101","0110","0111"]
num = input("Decimal: ")
BCDValue = ""
valid = True
for i in range(len(num)):
if num[i].isdigit():
if(int(num[i])>= 0 and int(num[i])<8):
BCDValue += BCD[i]+" "
else:
valid = False
break;
else:
valid = False
break;
if(valid):
print(BCDValue)
else:
print("Invalid")
Explanation:
This initializes the BCD corresponding value of the decimal number to a list
BCD = ["0001","0010","0011","0100","0101","0110","0111"]
This gets input for a decimal number
num = input("Decimal: ")
This initializes the required output (i.e. BCD value) to an empty string
BCDValue = ""
This initializes valid input to True (Boolean)
valid = True
This iterates through the input string
for i in range(len(num)):
This checks if each character of the string is a number
if num[i].isdigit():
If yes, it checks if the number ranges from 0 to 7 (inclusive)
if(int(num[i])>= 0 and int(num[i])<8):
If yes, the corresponding BCD value is calculated
BCDValue += BCD[i]+" "
else:
If otherwise, then the input string is invalid and the loop is exited
valid = False
break;
If otherwise, then the input string is invalid and the loop is exited
else:
valid = False
break;
If valid is True, then the BCD value is printed
if(valid):
print(BCDValue)
If otherwise, it prints Invalid
else:
print("Invalid")

Implement the function _isPalindrome() in palindrome.py, using recursion, such that it returns True if the argument s is a palindrome (ie, reads the same forwards and backwards), and False otherwise. You may assume that s is all lower case and doesn’t include any whitespace characters.
Answer:
The function is as follows:
def _isPalindrome(stri) :
if len(stri) == 0:
return True
if stri[0] == stri[len(stri) - 1]:
return _isPalindrome(stri[1:len(stri) - 1])
else:
return False
Explanation:
This defines the function
def _isPalindrome(stri) :
If the string is empty, then it is palindrome
if len(stri) == 0:
return True
This checks if the characters at alternate positions are the same.
If yes, it calls the function to check for other characters
if stri[0] == stri[len(stri) - 1]:
return _isPalindrome(stri[1:len(stri) - 1])
If otherwise, the string is not palindrome
else:
return False
The L-exclusion problem is a variant of the starvation-free mutual exclusion problem. We make two changes: as many as L threads may be in the critical section at the same time, and fewer than L threads might fail (by halting) in the critical section. An implementation must satisfy the following conditions:_____.
L-Exclusion: At any time, at most L threads are in the critical section.
L-Starvation-Freedom: As long as fewer than L threads are in the critical section, then some thread that wants to enter the critical section will eventually succeed (even if some threads in the critical section have halted).
Modify the n-process Bakery mutual exclusion algorithm to turn it into an L-exclusion algorithm. Do not consider atomic operations in your answer. You can provide a pseudo-code solution or written solution.
Answer:
The solution is as follows.
class LFilters implements Lock {
int[] lvl;
int[] vic;
public LFilters(int n, int l) {
lvl = new int[max(n-l+1,0)];
vic = new int[max(n-l+1,0)];
for (int i = 0; i < n-l+1; i++) {
lvl[i] = 0;
}
}
public void lock() {
int me = ThreadID.get();
for (int i = 1; i < n-l+1; i++) { // attempt level i
lvl[me] = i;
vic[i] = me;
// rotate while conflicts exist
int above = l+1;
while (above > l && vic[i] == me) {
above = 0;
for (int k = 0; k < n; k++) {
if (lvl[k] >= i) above++;
}
}
}
}
public void unlock() {
int me = ThreadID.get();
lvl[me] = 0;
}
}
Explanation:
The code is presented above in which the a class is formed which has two variables, lvl and vic. It performs the operation of lock as indicated above.
