C#: Perform an operation on +, -, *, x, / and displays the result of that operation

Last update on August 20 2025 12:39:40 (UTC/GMT +8 hours)

Write a C# Sharp program that takes two numbers as input and performs an operation (+,-,*,x,/) on them and displays the result of that operation.

Sample Solution:-

C# Sharp Code:

using System;

public class Exercise4
{
    public static void Main()
    {
        // Declaration of variables for input
        int x, y;
        char operation;

        // User input for the first number
        Console.Write("Input first number: ");
        x = Convert.ToInt32(Console.ReadLine());

        // User input for the operation to perform (+, -, *, /)
        Console.Write("Input operation: ");
        operation = Convert.ToChar(Console.ReadLine());

        // User input for the second number
        Console.Write("Input second number: ");
        y = Convert.ToInt32(Console.ReadLine());

        // Conditionals to perform the arithmetic operation based on the operator entered
        if (operation == '+')
            Console.WriteLine("{0} + {1} = {2}", x, y, x + y);
        else if (operation == '-')
            Console.WriteLine("{0} - {1} = {2}", x, y, x - y);
        else if ((operation == 'x') || (operation == '*'))
            Console.WriteLine("{0} * {1} = {2}", x, y, x * y);
        else if (operation == '/')
            Console.WriteLine("{0} / {1} = {2}", x, y, x / y);
        else
            Console.WriteLine("Wrong Character"); // Displayed if an invalid operator is entered
    }
}

Sample Output:

Input first number: 4                                                                                         
Input operation: *                                                                                            
Input second number: 4                                                                                        
4 * 4 = 16
