Then whichever function you're trying to use probably doesn't live in <cstdio>. Which function are you actually trying to use?

[adibahuda]

just void display();
does this function doesn't live in <cstdio> function????

[Moschops]

Here is cstdio. Take a look.

http://cplusplus.com/reference/clibrary/cstdio/

No such function.

Or you are not specifying the namespace.

using std::printf;
// ...
printf("=D");

or

std::printf("=D");

But there are probably better things to use instead of the functions in this header.
