Thread: Code does not work when 'run' ing it but works fine while debugging?

I have a code to convert a number to words(e.g. 31415-->Thirty one thousand four hundred fifteen) The code compiles with no errors/warnings and outputs correctly when debugging. But nothing happens when I 'Run' it. I'm using Code::Blocks. Any help would be appreciated!

Code:

int main (void)
{
int *dataptr = NULL,num,digit_count;
STACK* stack = create();
dataptr = malloc(sizeof(int));
printf("Enter number");
scanf("%d",&num);
while (num!=0)
{
    *dataptr = num%10;
    num = num/10;
    push (stack,dataptr);
    digit_count ++;
};
convert (stack,digit_count);
return 0;

}


void convert (STACK* stack,int digit_count)
{
int* datainptr1=NULL,*datainptr2=NULL;
datainptr1 = (int*)pop(stack);
switch (digit_count)
{
    case 1: //some function
    break;

    case 2:
    {
        if (*datainptr1 == 1)
        {
        datainptr2 = (int*)pop(stack);
        switch (*datainptr2)
        {
            case 1:printf ("Eleven");
            break;
            case 2:printf ("Twelve");
            break;
            case 3:printf ("Thirteen");
            break;
            case 4:printf ("Fourteen");
            break;
            case 5:printf ("Fifteen");
            break;
            case 6:printf ("Sixteen");
            break;
            case 7:printf ("Seventeen");
            break;
            case 8:printf ("Eighteen");
            break;
            case 9:printf ("Nineteen");
            break;
            }
        }
        else
        {
           //more
        }

    }
    break;
}
}

The 'pop' function in a custom header file(for stack simulation) returns a void* by the way. Any ideas on what's wrong?
