c - warning: implicit declaration of function ‘printf’

Question

I know alot of similar questions were asked before but i couldn\'t find something that would fix this warning i get:

MyIntFunctions.c:19:2: warning: implicit         


        

Answer 1

You need to include a declaration of the printf() function.

#include <stdio.h>

Answer 2

You need to include the appropriate header

#include <stdio.h>

If you're not sure which header a standard function is defined in, the function's man page will state this.

Answer 3

the warning or error of kind IMPLICIT DECLARATION is that the compiler is expecting a Function Declaration/Prototype..

It might either be a header file or your own function Declaration..
