#include<stdio.h>

int main()
{
    int num, count;

    printf("Enter a positive number\n");
    scanf("%d", &num);

    printf("\nNatural numbers from 1 to %d are:\n", num);

    for(count = 1; count <= num; count++)
    {
        printf("%d\t", count);
    }

C Program to Print Natural Numbers from 1 to N using for loop

Logic To Print Natural Numbers from 1 to N using for loop

We start by assigning 1 to variable count. Now we ask the user to enter a positive number. Now for loop keeps executing until value of count is less than or equal to user entered value. Inside for loop we printout the value of count and then increment the value of count by one for each iteration of loop.

This way we printout all the natural numbers from 1 to N.
