Implicit Declaration of Function Printf()

[lucasbeirer]

When i try to compile the following program, it says
"warning: implicit declaration of function 'printf'"
Heres the source code

#include <stdio.h>
 
int main(void)
{
    prinf("Hello World");
    return 0;
 
}

Two reasons i can think of
1. In your actual source code you have not included

#include <stdio.h>
 

2. The installation is not proper and the compiler is not able to find the stdio.h file or may be it is pointing to different stdio.h file

Actually, it's printf not prinf.

In the warning message it correctly refers to printf.so, I was not sure which is correct?

An implicit declaration means to call a function without previously telling the compiler that this is a valid function. You tell the compiler the function is valid by a)coding the function before you call it the first time or b)using a function prototype if the code for the function does not appear before the first call.


There is no way that the compiler would know you meant printf when prinf is a perfectly good function name.

Maybe you could post your warning.
