C program to print product of the digits of the number(Using For Loop)

Solution : Without using function
Program/Source Code

#include <stdio.h>

int main()
{
    int n,p=1,d;
    printf("Enter any no ");
    scanf("%d",&n);
    for(;n>0;)
    {
        d=n%10;
        p=p*d;
        n=n/10;
    }
    printf("Product of digits = %d",p);
    return 0;
}

Output:

Enter any no 1234
Product of digits = 24

Solution : Using function Passing Arguments
Program/Source Code

#include <stdio.h>
void check(int n)
{
    int p=1,d;
    while(n>0)
    {
        d=n%10;
        p=p*d;
        n=n/10;
    }
    printf("Product of digits = %d",p);
}

int main()
{
    int n;
    printf("Enter any no ");
    scanf("%d",&n);
    check(n);
    return 0;
}

Output:

Enter any no 256
Product of digits = 60
