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 declaration of function ‘printf’ [-Wimplicit-function-declaration]
Occurs here:
void IntPrint (const void *key)
{
printf("%d", *(int*)key); // line 19
printf("\t-->\t");
}
and a similar warning:
MyStringFunctions.c:22:2: warning: implicit declaration of function ‘printf’ [-Wimplicit-function-declaration]
void StringPrint (const void *key)
{
printf("%s",(char*)key); //line 22
printf("\t-->\t");
}
I really want to understand what is wrong so i won't do that again in the future.
This question is related to
c
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..
You need to include a declaration of the printf()
function.
#include <stdio.h>
