Thread: My third C program

A regular number is a positive integer all of whose prime factors are in the set {2, 3, 5}. (1
is assumed to be regular.) Write a function regular that consumes a positive integer n and
prints out all regular numbers up to (and possibly including) n, one to a line, in increasing
order.
To submit: regular.c, regular-driver.c.

My regular.c contains

Code:

#include <math.h>
#include <stdio.h>

int regular(int n) {
            int m = n;
            while (n%5) {
                        m = m/5;
            }
            while (m%3) {
                        m = m/3;
            }
            while (m%2) {
                        m = m/2;
            }
            if (m == 1) {
                        printf("%d ", n);
                        return regular(n-1);
            }
}

my regular-driver.c contains

Code:

#include <stdio.h>

#include "regular.h"

int main() {
            regular(60);
            return 0;
}

I don't have an error but once I run regular. Nothing happens no output.

I believe it is because it never reaches the if statement.
I know that 60 is a regular number because 5*3*2*2 = 60
So it should atleast printf that 60 is regular.

Any help is appreciated.

It works now thank you very much
