#include<iostream>
using namespace std;
int main()
{
double height, width;
cout<<"Enter wall height (feet): ";
cin>>height;
cout<<"Enter wall width (feet): ";
cin>>width;
//1
double area;
area = width * height;
cout<<"Wall area: "<<area<<" square feet"<<"\n";
//2
const double gallon = area/350.0;
cout<<"Paint needed: "<<gallon<<" gallons"<<"\n";
//3
cout << "Cans needed :" << round(gallon) << " can(s)";
return 0;
}
Explanation:
This line declares the height and width as double
double height, width;
This line prompts user for height
cout<<"Enter wall height (feet): ";
This line gets user input for height
cin>>height;
This line prompts user for width
cout<<"Enter wall width (feet): ";
This line gets user input for width
cin>>width;
//1 Question 1 begins here
This line declares area as double
double area;
The line calculates area
area = width * height;
The line prints the calculated area
cout<<"Wall area: "<<area<<" square feet"<<"\n";
//2 Question 2 begins here
This line declares and calculates gallon as a constant double variable
const double gallon = area/350.0;
This line prints the calculated gallon
cout<<"Paint needed: "<<gallon<<" gallons"<<"\n";
//3 Question 3 begins here
This line rounds gallon to nearest whole number and prints the result
cout << "Cans needed :" << round(gallon) << " can(s)";

8. What is the correct syntax of declaring arrays of pointers of integers of size 10
in C++?
a) int arr = new int[10];
b) int **arr = new int*[10];
c) int *arr = new int[10];
d) int *arr = new int [10];
Answer:
(b) int **arr = new int*[10];
Explanation:
An array of pointers is simply an array containing pointer variables. These pointer variables may be Strings, integers, doubles e.t.c
To declare such arrays of pointers, for example, of integers, in C++, we write;
int **arr = new int*[10];
The left hand side of the above code snippet i.e int ** arr, suggests that arr is a pointer that points to a pointer to integer variables.
The right hand side i.e new int* [10], creates a new array of 10 integer pointer variables.
Now, put together, int **arr = new int*[10] will create/declare an array of pointers of integers having a size of 10.
Which delivery model is an example of a cloud computing environment that provides users with a web based email service?
a. SaaS
b. PaaS
c. IaaS
Answer:
a. SaaS
Explanation:
Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.
Cloud computing comprises of three (3) service models and these are;
1. Platform as a Service (PaaS).
2. Infrastructure as a Service (IaaS).
3. Software as a Service (SaaS).
Software as a Service (SaaS) can be defined as a cloud computing delivery model which involves the process of making licensed softwares available over the internet for end users on a subscription basis through a third-party or by centrally hosting it.
Hence, Software as a Service (SaaS) is an example of a cloud computing environment that provides users with a web based email service.

Assign searchResult with a pointer to any instance of searchChar in personName.
#include
#include
int main(void) {
char personName[100] = "Albert Johnson";
char searchChar = 'J';
char* searchResult = NULL;
/* Your solution goes here */
if (searchResult != NULL) {
printf("Character found.\n");
}
else {
printf("Character not found.\n");
}
return 0;
}
Answer:
Here it the solution statement:
searchResult = strchr(personName, searchChar);
This statement uses strchr function which is used to find the occurrence of a character (searchChar) in a string (personName). The result is assigned to searchResult.
Headerfile cstring is included in order to use this method.
Explanation:
Here is the complete program
#include<iostream> //to use input output functions
#include <cstring> //to use strchr function
using namespace std; //to access objects like cin cout
int main() { // start of main() function body
char personName[100]; //char type array that holds person name
char searchChar; //stores character to be searched in personName
char* searchResult = nullptr; // pointer. This statement is same as searchResult = NULL
cin.getline(personName, 100); //reads the input string i.e. person name
cin >> searchChar; // reads the value of searchChar which is the character to be searched in personName
/* Your solution goes here */
searchResult = strchr(personName, searchChar); //find the first occurrence of a searchChar in personName
if (searchResult != nullptr) //if searchResult is not equal to nullptr
{cout << "Character found." << endl;} //displays character found
else //if searchResult is equal to null
{cout << "Character not found." << endl;} // displays Character not found
return 0;}
For example the user enters the following string as personName
Albert Johnson
and user enters the searchChar as:
J
Then the strchr() searches the first occurrence of J in AlbertJohnson.
The above program gives the following output:
Character found.

Write a Python program that prints your name, CS classes taken (or other relevant experience), and the date on separate lines. Use one variable each for the month, day, and year (3 total). Make sure there are no spaces between the forward slash and numbers. Submit the .py file. Sample Run: My name is Steven Allbee I have taken CS 10 - Python Programming Today's date is 1/17/19
Answer:
The program in Python is as follows:
name = input("Name: ")
course = input("Course: ")
month = input("Month: ")
day = input("Day: ")
year = input("Year: ")
ddate = (month+"/"+day+"/"+year).replace(" ", "")
print("My name is ",name)

print("Today's date is ",ddate)
Explanation:
This line prompts user for name
name = input("Name: ")
This line prompts user for course classes taken
course = input("Course: ")
This line prompts user for month
month = input("Month: ")
This line prompts user for day
day = input("Day: ")
This line prompts user for year
year = input("Year: ")
This line calculates the date and remove all blank spaces
ddate = (month+"/"+day+"/"+year).replace(" ", "")
The next three lines print the user inputs
print("My name is ",name)
print("I have taken ",course)
print("Today's date is ",ddate)

Assume that IBM has a relatively low unit market share for blockchain technology and that the blockchain technology industry’s growth rate is extremely high (averaging 30% per year). Using the BCG business portfolio analysis framework, blockchain technology would be classified as a ________ SBU for IBM.
Answer:
The blockchain technology would be classified as a Question Mark strategic business unit (SBU)
Explanation:
The Boston Consulting Group Matrix was first developed towards the end of the nineteenth century for use in analysing the performance and classifying products and business units.
This tool is still very relevant today.
The Matrix is made up of four quadrants:
Top Left - Question Mark
Top Right - Star
Bottom Left - Dog
Bottom Right - Cashcow
A Question Mark product or business unit is one which at the onset has a very little market share in an environment with a high growth rate. It is at the onset also characterised by losses and will need more time and money for it to bloom. If invested and nurtured can become a start and then a cash cow. There is also a risk that it will end up a white elephant business unit or product if it is not nurtured properly thus leading to losses.

Which of the following best describes how computing devices represent information?
A. A computer will either represent information as bits or bytes but not both
B. A computer represents data as a byte which is either a 0 or a 1
C. A computer represents data as bits which is either a 0 or a 1
D. A computer represents information as bits which contain 8 bytes.
Answer:
The answer is "C"
Explanation:
In the computer system, the data which separates a data object into relevant concepts is known as data representation. In the representation of data, it uses the binary digits, that are in the form of '0 and 1'. It is used by computers to store information and these numbers are also known as bits, and wrong choices can be defines as follows:
In option A, It is wrong because when we see the file details it shows both. In option B, It's incorrect because the smallest unit of data representation is bits. In option D, It is incorrect because bits includes only "0 and 1".
