.NET Practical Slip 3 Q A

This C#.NET program demonstrates how to create and use a user-defined function to calculate the sum of two numbers. It helps in understanding function creation, parameter passing, and method calling in C#.

Slip 3 Q.A) Write a program in C# .Net to create a function for the sum of two numbers. 15 Marks

Answer:

Algorithm / Logic

1. Start the program.
2. Create a function named Sum() that accepts two integer parameters.
3. Inside the function, add the two numbers and return the result.
4. In the Main() method, accept two numbers from the user.
5. Call the Sum() function by passing the two numbers as arguments.
6. Display the returned result.
7. Stop the program.

Source Code

using System;

namespace SumOfTwoNumbers
{
    class Program
    {
        static int AddTwoNumbers(int num1, int num2)
        {
            return num1 + num2;
        }

        static void Main(string[] args)
        {
            int number1 = 10;
            int number2 = 20;
            int sum = AddTwoNumbers(number1, number2);
            Console.WriteLine("The sum of " + number1 + " and " + number2 + " is: " + sum);
            Console.ReadLine();
        }
    }
}
