This C# program calculates the sum of the first 50 natural numbers. Natural numbers are the positive integers starting from 1.

## Problem Statement

Write a C# program that calculates and displays the sum of the first 50 natural numbers. Natural numbers are positive integers starting from 1 and continuing indefinitely. Your program should use a `for`

loop to iterate through the first 50 natural numbers, accumulate their sum, and then output the result.

## C# Program to Find the Sum of First 50 Natural Numbers using For Loop

using System; namespace SumOfFirst50NaturalNumbers { class Program { static void Main(string[] args) { int sum = 0; // Using a for loop to iterate through the first 50 natural numbers for (int i = 1; i <= 50; i++) { sum += i; } Console.WriteLine("The sum of the first 50 natural numbers is: " + sum); } } }

## How it Works

**Initialization**:- We start by declaring an integer variable called
`sum`

and initialize it to 0. This variable will be used to store the cumulative sum of the natural numbers.

- We start by declaring an integer variable called
**For Loop**:- We use a
`for`

loop to perform a series of actions repeatedly. In this case, the loop will execute 50 times, starting from`i = 1`

and ending when`i`

becomes greater than 50. `int i = 1;`

initializes a loop variable`i`

to 1, which is the first natural number.`i <= 50`

is the loop condition. The loop will continue as long as`i`

is less than or equal to 50.`i++`

is the increment statement, which increases`i`

by 1 after each iteration.

- We use a
**Loop Body**:- Inside the loop, we have a single statement:
`sum += i;`

. This statement adds the current value of`i`

to the`sum`

variable.- In the first iteration,
`i`

is 1, so we add 1 to`sum`

. - In the second iteration,
`i`

is 2, so we add 2 to`sum`

. - This process continues until the loop completes all 50 iterations.

- In the first iteration,

- Inside the loop, we have a single statement:
**Accumulation of Sum**:- As the loop iterates, the
`sum`

variable accumulates the sum of the first 50 natural numbers.

- As the loop iterates, the
**Printing the Result**:- After the
`for`

loop finishes executing, we use`Console.WriteLine`

to display the result. - We print a message, â€œThe sum of the first 50 natural numbers is: â€œ, followed by the value of the
`sum`

variable, which contains the sum we calculated in the loop.

- After the
**Program Execution**:- When you run the program, it initializes
`sum`

to 0, enters the`for`

loop, adds the numbers from 1 to 50 to`sum`

, and then displays the final sum in the console.

- When you run the program, it initializes
