Hello,

I have made a programm which calculated the GCD of two numbers.
Code:

#include        <stdio.h>


int
main ( int argc, char *argv[] )
{
        int getal1, getal2, tmp, uitkomst, rest ;

        tmp = 0 ;
        printf ("Enter the two numbers where the GCD must be calculated  \n")
        printf ("Please first the little number and then the greatest number. ");
        scanf ("%d %d", &getal1, &getal2) ;
        uitkomst = getal2 / getal1 ;
        rest  = getal2 - uitkomst * getal1;
        while (rest > 1)
                {
                        tmp = getal1 ;
                        getal2 = getal1 ;
                        getal1 = rest ;
                        uitkomst = getal2/getal1 ;
                        rest = getal2 - uitkomst * getal1;
                }
        if (rest == 0)
                printf("The GCD is %d",getal1 );
        else
                printf("There is no GCD");
        return 0 ;
For me it works.
But I wonder if you experts have anything to say about the programm.
