Question

needs to be written in c++ code

For this assessment, you will develop an application. The application should allow the user to perform a simple calculation. (You should determine the calculation that the user should be able to perform with the application; the user simply inputs or navigates through information to be able to calculate it.)

The user entries will be saved in the appropriate data type, and variables will be used to perform the calculation and return the result back to the user. These projects are to be completed in your Integrated Development Environment (IDE) (such as Visual Studio), and completed as executable C++ applications so you can compile and run them to see if you have any errors. Attach your "zipped" project folders with your submission.

Answer 1

Cpp Code:

#include <iostream>

using namespace std;

int main()
{
//Displaying the operations
cout << "1. Addition\n";
cout << "2. Subtraction\n";
cout << "3. Multiplication\n";
cout << "4. Division\n";
cout << "Enter the calculation to perform" << endl;
char choice;
//prompting the user
cin >> choice;
//getting the two numbers
cout << "Enter two numbers\n";
double num1, num2;
cin >> num1;
while(1){
cin >> num2;
if (choice == '4' && num2==0){ //checking if divisor is not 0
cout << "Divisor should not be 0...Try again...Enter number 2\n";
}else{
break;
}
}
//Performing the operation
switch(choice){
case '1':
cout << "Answer is: " << num1 + num2;
break;
case '2':
cout << "Answer is: " << num1 - num2;
break;
case '3':
cout << "Answer is: " << num1 * num2;
break;
case '4':
cout << "Answer is: " << num1 / num2;
break;
default: //If user enters invalid operation
cout << "Invalid Operation\n";
}
return 0;
}

Sample Output:

1. Addition
2. Subtraction
3. Multiplication
4. Division
Enter the calculation to perform
3
Enter two numbers
4 6
Answer is: 24
