C# Program with a Function to Sum Two Numbers

This C# program defines a function called Sum that accepts two integer parameters, adds them together, and returns the result. The Main method initializes two integer variables (x and y), calls the Sum function with those variables as arguments, and displays the result using Console.WriteLine. This example demonstrates how to pass parameters to a function and how to return a value from that function in C#.

Functions in C#

Objective

1. Define a function called Sum that takes two integers as parameters.
2. Inside the Sum function, return the sum of the two integers.
3. In the Main method, declare two integer variables, x and y, and initialize them with the values 3 and 5, respectively.
4. Call the Sum function from Main with x and y as parameters.
5. Display the result of the Sum function using Console.WriteLine.

Write a C# program whose Main must be like this: 

public static void Main()

{

     int x= 3;

     int y = 5;

     Console.WriteLine( Sum(x,y) );

}

Example C# Exercise

 Copy C# Code 
using System;

class Program
{
    // Main method where the program execution begins
    public static void Main()
    {
        // Declare two integer variables and initialize them
        int x = 3;
        int y = 5;

        // Call the Sum function with x and y as parameters and display the result
        Console.WriteLine(Sum(x, y));
    }

    // Function to sum two integers and return the result
    public static int Sum(int num1, int num2)
    {
        // Return the sum of the two integers
        return num1 + num2;
    }
}
