QuickC Compiler Error

I just reinstalled my old copy of QuickC, and have been
playing around with converting some short programs. The
problem I have is that when I compile in memory I get
a C2175 error. This means that the function is invalid
and I shold include or define the function. Evidently
this only happens with short progs compiled in memory and isnt supposed to occur when doing to exe etc.

I cut things back to the point where I was only working
with 3-4 lines of code (gen a rand number and display) but
I still got the same error. My paths are good etc and in
the case of the include's the prog is finding the right one.
So how Can I work around this, so I can compile to memory
and check my code. It says I should include the lib (which i have) or define the function. Is there another way around this?

Give us a tiny but complete program displaying the error.

As requested here is a very short chunk of code
that will produce the C2175 error.

#include <stdlib>
main()
{
    int x;
    for (x = 1; x <= 20; x++)
    printf("Iteration %d, rand = %d", x, rand());
    }

If I try to define rand say as rand(void) I get not enough
paramitors,
My guess is that it's not your compiler that's complaining --
it's your linker. It can't find a definition of the rand() function,
because you didn't supply it with the corresponding library.
Check the linker options ...

Just a guess though; I know nothing about quickC

BTW: change your first line to:

#include <stdlib.h>

kind regards,

The <stdlib.h> is correct in my code. However typing
it in again managed to make the odd error. Code I am
compiling has no syntax errors (unlike my typing ;-])

How about adding:
    #include <stdio.h>
Does this help?
Since this remains unanswered, I'll agree with the previous posted answers and add a run-time comment. Your code should compile cleanly by including <stdio.h> for the printf() prototype and <stdlib.h> for the rand() prototype. Run time Comment: In addition, you should precede the use of rand() with srand() to seed the random number generator. This shouldn't affect compiling, however.

Maybe your compiler is complaining about the main() declaration having no parameters?

Check you code carefully -- especially the first two include statements. It should look like this:

#include <stdio.h>
#include <stdlib.h>
int main( int argc, char *argv[])
{
   int x;

   srand( 1 );   /* instead of 1, use an unsigned seed value */
                 /* that changes, like */
                 /* srand(( unsigned )time( NULL )); */
                 /* time() needs time.h included. */
   for( x = 1; x <= 20; x++ )
      printf( "Iteration %d, rand = %d", x, rand());
   return( 0 );
}
