Source Code: C Program to Print Natural Numbers Between Two Numbers using While loop

 
#include < stdio.h >

int main()
{
    int min, max;

    printf("Enter 2 positive numbers\n");
    scanf("%d%d", &min, &max);

    printf("Natural numbers between %d and %d are:\n", min, max);
    while(min <= max)
    {
        printf("%d  ", min);
        min++;
    }

    printf("\n");

    return 0;
}

Output 1:
Enter 2 positive numbers
10
20
Natural numbers between 10 and 20 are:
10 11 12 13 14 15 16 17 18 19 20

Output 2:
Enter 2 positive numbers
25
35
Natural numbers between 25 and 35 are:
25 26 27 28 29 30 31 32 33 34 35

Logic To Print Natural Numbers Between Two Numbers using While loop

We ask the user to enter 2 numbers, and store it inside variables min and max. While loop keeps iterating till min is less than or equal to max. Inside while loop we keep incrementing the value of variable min by one for each iteration. We also display the value of min to the console window.
