Thread: loop problem

Hello,

I have to find the greatest number a user enters.
When the user enters a ) or a number smaller then 0 then the output has to stop,
So I made this :

Code:

#include        <stdio.h>


int
main ( int argc, char *argv[] )
{
        float getal, grootste  ;
        getal = grootste = 1 ;
        do
        {
                printf("Enter a number : ");
                scanf ("%f", &getal);
                printf ("Ingevoerde getal : %f", getal) ;
        }
        while (getal <=0);
        printf ("Het grootste getal is %f", grootste);
        return 0 ;
}                               /* ----------  end of function main  ---------- */

But when the user enters one number the loop stops.
What is my thinking error here ?
