Program to Calculate the Sum of Natural Numbers - (C# Basic Programs)

Calculating the sum of natural numbers is a common programming exercise that helps improve problem-solving skills. In this tutorial, we will discuss a program to calculate the sum of natural numbers using C# programming language.

Syntax

The syntax for calculating the sum of natural numbers in C# is as follows:

int sum = 0;
for (int i = 1; i <= n; i++)
{
    sum += i;
}

Here, n is the number of natural numbers to be added, and sum is the variable used to store the sum of natural numbers.

Example

using System;

public class Program
{
    public static void Main()
    {
        int n = 10;
        int sum = 0;

        for (int i = 1; i <= n; i++)
        {
            sum += i;
        }

        Console.WriteLine("Sum of first {0} natural numbers: {1}", n, sum);
    }
}

Output:

Sum of first 10 natural numbers: 55

Explanation

The program first initializes n to the number of natural numbers to be added, in this case, 10. Then, a for loop is used to iterate from 1 to n. Inside the loop, the variable sum is incremented by the current value of i. Finally, the program prints the sum of the first n natural numbers.

Use

Calculating the sum of natural numbers is useful when working with mathematical problems. This can be used as a building block for more complex algorithms.

Summary

In this tutorial, we discussed a program to calculate the sum of natural numbers using C# programming language. We have seen the syntax, example, explanation, and use of calculating the sum of natural numbers. By practicing this programming concept, programmers can improve their problem-solving skills and become better equipped to tackle complex coding challenges.
