[Solved] Switch Operations with C++

Switch Operations: The 4 basic mathematical operations are Addition, Subtraction, Multiplication and Divison. They are actually the core part in every mathematical problem.

Develop a program to perform all the mathematical operations in a menu driven format using a Switch case statement.

Input and Output format:

Refer sample input and output for formatting specifications.

Sample Input & Output 1 :

[All text in bold corresponds to input and the rest to output.]

Enter the first value :
12
Enter the second value :
12
Enter the choice from the menu
1.Addition
2.Subtraction
3.Multiplication
4.Division
1
The value after Addition is 24.

Sample Input & Output 2 :

Enter the first value :
12
Enter the second value :
12
Enter the choice from the menu
1.Addition
2.Subtraction
3.Multiplication
4.Division
2
The value after Subtraction is 0.

Sample Input & Output 3 :

Enter the first value :
12
Enter the second value :
12
Enter the choice from the menu
1.Addition
2.Subtraction
3.Multiplication
4.Division
3
The value after Multiplication is 144.

Sample Input & Output 4 :

Enter the first value :
12
Enter the second value :
12
Enter the choice from the menu
1.Addition
2.Subtraction
3.Multiplication
4.Division
4
The value after Division is 1.

Solution

#include <iostream>
using namespace std;

int main()
{
    int a, b;
    cout << "Enter the first value :" << endl;
    cin >> a;
    cout << "Enter the second value :" << endl;
    cin >> b;
    cout << "Enter the choice from the menu\n1.Addition\n2.Subtraction\n3.Multiplication\n4.Division\n";
    int choice;
    //sauravhathi
    cin >> choice;
    switch (choice)
    {
    case 1:
        cout << "The value after Addition is " << a + b << "." << endl;
        break;
    case 2:
        cout << "The value after Subtraction is " << a - b << "." << endl;
        break;
    case 3:
        // sauravhathi
        cout << "The value after Multiplication is " << a * b << "." << endl;
        break;
    case 4:
        cout << "The value after Division is " << a / b << "." << endl;
        break;
    default:
        cout << "Invalid choice" << endl;
        break;
    }
    return 0;
}
