Answer:
See explanation below and try out this code to see what exactly is happening
# Program
j = 3
z = { ] # empty dictionary
print(z)
z[2] = 1 # z
print(z)
z[7] = 3
print(z)
z[5] = 2
print(z) # prints out {2: 1, 7: 3, 5: 2}
for l in z:
print("Initial value of j = ", j)
print("Value of l(key) = ", l)
j += l
print("Updated value of j = ", j)
print("Final value of j=", j)
Explanation:
What you have is a dictionary object. We use { } to represent a dictionary. A dictionary consists of keys and values related to the keys. For example, you can have a dictionary which contains names of students and their GPAs
This is declared as
student_grades = {"Amy": 4.3, "Zach":4.0", "Bill": 3.2}
The names are referred to as keys and the GPA as values
You can also have both key and value as integers. Fir example you could store the cubes of numbers from 1 to 5 in a dictionary
cubes = {1: 1, 2:8, 3: 27, 4: 64, 5:125}
If you wanted to add the cube for 6 then you would use cubes[6] = 216 This creates a new entry in the dictionary 6:216 so that the dictionary is now
cubes = {1: 1, 2:8, 3: 27, 4: 64, 5:125, 6:216}
In this short program here is what is happening
j = 3 # variable j created and value set to 3
z = { } # this creates an empty dictionary named z
z[2] = 1 #adds an entry with key = 2 and value = 1; z = {2 : 1}
z[7} = 3 #key 7 and value 2 added => z = {2 : 1, 7 : 3}
z[5] = 2 #key 5, value 2 => z = {2: 1, 7 : 3, 5 : 2}
So now there are 3 entries in the dictionary i.e. 3 pairs of key-values
When you iterate through the dictionary as in
for l in z:
- you are actually iterating over the keys so l = 2, 7 and 5 on each iteration
So you are accumulating the key values
Here is what happens
First execution of loop => j = 3 , l = 2 (first key =2), j = 3 + 2 = 5
Second time: l = 7 (second key value) , j = 5 + 7 = 12
Third time: l = 5, j = 12 + 5 = 17
There is a lot more to dictionaries and sometimes it can get complicated. Suggest you search the internet for the same
Putting print() statements also helps you visualize what is happening. Code is provided in the answer section to help you

Note the warning I have provided about program (c)
Explanation:
Note that I have given complete programs. But you are asked to only write the C segments corresponding to that problem.
In the third program, I have used the syntax
case 100 ... 102:
printf("Paid\n");
break;
This means that if the number lies in the range 100 -102 the corresponding statement will execute.
However, this is not recognized by all C compilers!
You can explain to the professor that you found this on the internet (stackoverflow.com is a great site for programing resources)
Otherwise you will have to split up that into 3 separate case statements as follows:
switch(inv)
{
case 100:
printf("Paid\n");
break;
case 101:
printf("Paid\n");
break;
case 102:
printf("Paid\n");
break;

Searching an Array for an Exact Match
Summary
In this lab, you use what you have learned about searching an array to find an exact match to complete a partially prewritten C++ program. The program uses an array that contains valid names for 10 cities in Michigan. You ask the user to enter a city name; your program then searches the array for that city name. If it is not found, the program should print a message that informs the user the city name is not found in the list of valid cities in Michigan.
The file provided for this lab includes the input statements and the necessary variable declarations. You need to use a loop to examine all the items in the array and test for a match. You also need to set a flag if there is a match and then test the flag variable to determine if you should print the the Not a city in Michigan. message. Comments in the code tell you where to write your statements. You can use the previous Mail Order program as a guide.
Instructions
Ensure the provided code file named MichiganCities.cpp is open.
Study the prewritten code to make sure you understand it.
Write a loop statement that examines the names of cities stored in the array.
Write code that tests for a match.
Write code that, when appropriate, prints the message Not a city in Michigan..
Execute the program by clicking the Run button at the bottom of the screen. Use the following as input:

(while-loop). Generate a random integer from 1 to 100. Prompt the user to guess the number. Display "Too high" or "Too low", depending on the guess. When the user guesses the right number, display "You got it!". You must keep track of the number of times the user takes to guess the number and report it when the number is correct.
Hints: To generate the random number, use the one below:
import random as rd
answer = rd.randrange(1,101)
TEST CASES: Suppose the number to guess is 40.
Enter guess: 1-100: 50
Too high!
Enter guess: 1-100: 25
Too low!
Enter guess: 1-100: 35
Too low!
Enter guess: 1-100: 40
You got it!
You took 4 tries to guess the number.
Investment Problem: Multiplier Accumulator
Prompt the user to enter the initial investment amount, the annual interest, and the number of years for the investment.
Compute the balance that will be achieved at the end of each of the requested years. Round the balance to 2 decimal places.
Algorithm Hints:
Use a for-loop and range function to generate the year (1, 2, 3,…). The number of iterations is the number of years.
Using the formula (see below), compute the investment balance at the end of each year. Note that I know you could always use Python's exponentiation operator (**) to calculate the final result. But I want you to use iteration (looping) to find the answer! Hint: this is an example of an accumulator that uses multiplication.
For example, if you have $1 and get 4% interest, the amount at the end of the first five years would be:
FV = FV*(1 + APR)**year = 1 * (1 + 0.04) ** 1
FV = FV*(1 + APR)**year = 1 * (1 + 0.04) ** 2
FV = FV*(1 + APR)**year = 1 * (1 + 0.04) ** 3
FV = FV*(1 + APR)**year = 1 * (1 + 0.04) ** 4
FV = FV*(1 + APR)**year = 1 * (1 + 0.04) ** 5
etc.....
If you have an amount that is different than $1 (e.g., $10,000), multiplying $10,000 by the final FV quantity for each year will give you the future value for $10000.
Suggestion: to check your answer, use the exponentiation operator, calculate the result using the above formula, and compare that result with the one using your accumulator approach. The answers should be very close.
Also, you know that \n inside quotes generates a new line. Similarly, \t generates a tab stop, which you can use to generate the two columns in the output.
TEST CASE:
Enter initial investment: $5000
Enter interest rate: 2.5
Enter number of years: 29

Identify a true statement of array.find(callback [, thisArg]) method.
A. It tests whether the condition returned by the callback function holds for all items in array.
B. It returns the value of the first element in the array that passes a test in the callback function.
C. It tests whether the condition returned by the callback function holds for at least one item in array.
D. It returns the index of the first element in the array that passes a test in the callback function.
Option c is correct. It tests whether the condition returned by the callback function holds for at least one item in array.
Every element in the array is put through the supplied test by the provided function using the every() method. It gives back a Boolean result. Until it locates the element for which callback function returns a false result, the every method calls the given callback function once for each element present in the array.
The every method immediately returns false if such an element is discovered. Every returns true if callback function does not return a truthy value for any of the items.
Only for array indexes with assigned values is callbackFn triggered. For empty slots in sparse arrays, it is not called.
The value of the element, the index of the element, and the Array object being traversed are passed as the three arguments to callbackFn.

When Lowell Thomas produced 4,000 units during his 40 hour workweek and his regular rate of pay is $0.12 per unit, the overtime pay is C. $19.50 per hour.
What is overtime?The number of hours a worker works in excess of what is required for a typical workweek is calculated as their overtime rate. Depending on how overtime is defined by the labor laws of each country and jurisdiction, this rate may have various implications in each.
The overtime premium or the overtime rate of pay are typical names for overtime compensation. The most common overtime rate is time and a half, which is 50% more than the employee's hourly pay. It means that you will receive 1.5 times your regular hourly rate for every hour of overtime worked.
The overtime will be calculated thus:
Multiply $0.12 4,000 = $480
Multiply regular pay, $0.04 1,000 = $40
Add: Bonus pay, $480 + $40 = $520,
Divide $520/40 = $13.00/hr
Multiply the rate: $13.00 * 1.5 = $19.50/hr.
Therefore, the overtime is $19.50.

I am working on a code, but I keep getting a KeyError at line 71.

Answer:
multiple things probably
Explanation:
Well the code is a bit confusing to read since the lack of indents but I'll try my best to interpret what you were trying to do.
By the looks of the exception you provided, it seems that the key "I" does not exist in your dictionary: "vowels_dict"
Same thing applies with the key "a" not existing in your dictionary: "consonants_dict"
This makes sense since by looking at your code since they obviously don't exist in their respective dictionaries.
I tried pasting the code into VisualStudio to get a better look at it and I tried to fix the indenting and to ensure I got it correct I provided what I indented below
"
for i in range(len(hawaiian_word)):
if hawaiian_word[i] in valid_letters:
for key in hawaiian_word:
if hawaiian_word[i] in consonants_dict:
pronunciation += consonants_dict[key]
elif hawaiian_word[0][0] in vowels_dict:
pronunciation += vowels_dict_capitalized[key]
elif hawaiian_word[i] in vowels_dict:
pronunciation += vowels_dict[key]
elif hawaiian_word[i-2] in vowels_dict:
pronunciation += vowels_no_hyphen_dict[key]
if hawaiian_word[i] in invalid_letters:
print('Invalid word, ' + hawaiian_word[i] + ' is not a valid hawaiian character.')
"
So there are a few issues I noticed, and I'm not exactly sure how to fix them since I'm not exactly sure what is supposed to be done.
1.
hawaiian_word[0][0] is redundant and likely not what you think.
The think with this line is it first returns the first letter of hawaiian_word which is now a one letter string, and now you get the first letter of this one letter string... which is the same string. You're likely trying to do something else but like I explained I'm not quite sure.
2.
for key in hawaiian_word:
if hawaiian_word[i] in consonants_dict:
pronunciation += consonants_dict[key]
So no runtime error should occur here since you're first checking if the key even exists, but I noticed your dictionary is defined as: "consonants_dict = {
'p':'p',
'k':'k',
'h':'h',
'l':'l',
'm':'m',
'n':'n',
'w':'w',
'aw':'w',
'iw':'v',
'ew':'v',
'uw':'w',
'ow':'w'
}
"
and you'll notice the last few keys have two letters, except your for loop is going through the word one letter at a time so these keys will never be used.
3. (probably the cause of your error)
the line in each elif statement you have some code along the lines of: pronunciation += dictionary[key]
except this key is only being defined in the for loop and and never changes. This key is actually just going to be the last letter of the word in each case assuming the first if condition is met the for loop runs and key is finally set to the last letter and never changes until it runs again but even then after it finishes it is set to the last letter. This word is unlikely to be in each dictionary. I'm assuming you meant to actually do:
elif hawaiian_word[0][0] in vowels_dict:
key = hawaiian_word[0][0]
pronunciation += vowels_dict_capitalized[key]
elif hawaiian_word[i] in vowels_dict:
key = hawaiian_word[i]
pronunciation += vowels_dict[key]
elif hawaiian_word[i-2] in vowels_dict:
key = hawaiian_word[i-2]
pronunciation += vowels_no_hyphen_dict[key]
because you're checking if the current letter you're on in word is in the dictionary but then you use something completely different?
When a new encryption method is invented, you might think that it is kept secret so no one knows how to decode it. This actually isn’t the case; when someone invents a new encryption method, they publish the process and people begin trying to crack it. Why wouldn’t someone try to keep their encryption method secret? Explain your answer. Please help me!
Answer:
To test if the encryption method is effective.
Explanation:
If you kept a new encryption method secret, then when you use it hackers can try to crack it and whatever the encryption is protecting will be compromised. If you publish it beforehand while its not protecting anything, then you will know if its safe.
