Displaying first n natural numbers using different loops [ C Program Code]

The following C programming code displays the first n natural numbers on the screen. To carry out the process, we have used three different logics - the while loop, do while loop and the for loop.

 

Using while loop

	#include<stdio.h>
	int main()
	{
	int n,i=1;
	printf("Enter the limit: ");
	scanf("%d",&n);
	printf("The natural numbers are: ");
	while(i<=n)
	{
	printf("\t%d",i);
	i=i+1;
	}
	getch();
	return(0);
	}

Using do while loop

	#include<stdio.h>
	int main()
	{
	int n,i=1;
	printf("Enter the limit: ");
	scanf("%d",&n);
	printf("The natural numbers are: ");
	do
	{
	printf("\t%d",i);
	i=i+1;
	}
	while(i<=n);
	getch();
	return(0);
	}

Using for loop

	#include<stdio.h>
	int main()
	{
	int n,i;
	printf("Enter the limit: ");
	scanf("%d",&n);
	printf("The natural numbers are: ");
	for(i=1;i<=n;i++)
	{
	printf("\t%d",i);
	}
	getch();
	return(0);
	}
