Function Returning A Value - C# Programming Exercise

In this C# exercise, you are asked to write a program where the Main method must be like this:

public static void Main()
{
int x = 3;
int y = 5;
Console.WriteLine(Sum(x, y));
}

The goal of this exercise is to define the Sum function, which must accept two int parameters (in this case, the values 3 and 5) and return an int value, which will be the sum of those two numbers. This exercise is meant to practice creating functions that accept parameters and return values in C#, helping you understand how functions are used within the program's execution flow.

Function Returning A Value

Objective

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) );
}

"Sum" is a function that you must define and that will be called from inside Main. As you can see in the example, it must accept two integers as parameters, and it must return an integer number (the sum of those two numbers).

C# Exercise Example

Example Code Copied

// Importing the System namespace to access basic system functions
using System;

class Program
{
    // Function to calculate the sum of two integers and return the result
    public static int Sum(int a, int b)
    {
        // Return the sum of a and b
        return a + b;
    }

    // Main method to call the Sum function and display the result
    public static void Main()
    {
        // Declare two integer variables
        int x = 3;  // First number
        int y = 5;  // Second number

        // Call the Sum function with x and y as arguments, and display the result
        Console.WriteLine(Sum(x, y));  // This will print 8 (3 + 5)
    }
}
