Addition of Two Numbers in C# Program with Integer Values

// Addition of Two Numbers in C# Program with Integer Values
using System;

public class W3CW {
    // @It's the driver function
    static public void Main (string[] args) {
        Console.WriteLine("Enter two integer values::");
        int p = Convert.ToInt32(Console.ReadLine());
        int q = Convert.ToInt32(Console.ReadLine());
        
        // It will calculate the sum
        int r = p + q;
        
        // It will print the final output
        Console.WriteLine("\nResult:: " + p + " + " + q + " = " + r);
    }
}

Run

Output

Explanation

In the above program, we have taken two inputs 5 and 7 from the user via the system console. Then we applied the arithmetic operation on these values after that It will return the value 12 the output of the program.
