Thread: Compiler won't take #<stdlib.h>

I'm trying to make a guess the number program, and I've come up with this:

Code:

#include <stdio.h>
#include <stdlib.h>

int main()
{
 int a;
 int b;
 b=randomize(10);
 printf("%d\n",b);
 printf("Enter number: ");
 scanf("%d", &a);
 while (a != b)
          {
           printf("Wrong! Try again: ");
           scanf("%d", &a);
          }
printf("Congratulations! You guessed right!");
getchar();
getchar();
}

However, when I compile and I click the "linker" tab in the bottom of the screen I see the following messages:

Code:

d:\documents and settings\pim\mijn documenten\c\guessnum.o(.text+0x75):guessnum.c: undefined reference to `randomize'

I'm using the Bloodshed Dev C++ compiler, version 4.

Could anyone tell me what I have done wrong here?

Thank You.

isn't the function called rand()?

Looks like that page was using Turbo C, which apparently has a lot of non-standard crap in it.
