C program to print numbers from 1 to N using while loop

This is an example of while loop in C programming language - In this C program, we are going to print numbers from 1 to N using while loop.
Submitted by IncludeHelp, on March 07, 2018

Here, N is the limit of the number, for example – if you want to print the numbers from 1 to 10 or 1 to 100 then 10 or 100 will be the value of N. In this C program, N will be entered by the user.

To print the numbers from 1 to N,

We will declare two variables 1) for loop counter (number) and 2) for limit (n).
We will check the condition whether loop counter is less than or equal to N, if condition is true numbers will be printed.
If condition is false – loop will be terminated.

Program to print numbers from 1 to N using while loop in C

#include <stdio.h>

int main()
{ 

	//loop counter declaration
	int number;
	//variable to store limit /N
	int n;
	
	
	//assign initial value 
	//from where we want to print the numbers
	number =1;
	
	//input value of N
	printf("Enter the value of N: ");
	scanf("%d",&n);
	
	//print statement
	printf("Numbers from 1 to %d: \n",n);
	
	//while loop, that will print numbers 
	//from 1 to n
	while(number <= n)
	{
		//printing the numbers
		printf("%d ",number);
		//increasing loop counter by 1
		number++;
	}
	
	return 0;
}

Output

Enter the value of N: 25 
Numbers from 1 to 25: 
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 
16 17 18 19 20 21 22 23 24 25
