incompatible implicit declaration of built-in function ‘exit’

C

tried to compile a simple hello world program:

Code:

---

#include<stdio.h>

int main()
{
        printf("Hello World\n"0;
        exit(0);
}

---

when I compile the above code I get the following error:

Code:

---

$ gcc hello.c
hello.c: In function ‘main’:
hello.c:6: warning: incompatible implicit declaration of built-in function ‘exit’

---

Please tell me where am I going wrong?

exit() is in <stdlib.h>, be sure to include it.

BTW, you can just use return 0 from main(), no extra header files required.

That helps! Thank you.
