'printf': identifier not found

Question

I have included stdio.h into my C++ project, why am I still getting this error? Also, after I added #include , printf(), in my code, was no longer underlined in red to suggest that there was any error.

Also, I would like to use the function, format(). Which library is that found in?

Answer 1

you must include stdio.h instead of cstdio.h

#include <stdio.h>

Answer 2

Use
#include< cstdio>
using namespace std;
after that you can use printf()
