C++ Help

Hey, I'm making a program in C++ I know the basics of C++, well I know enough to do what I'm doing. My problem is, when I use system I get an error saying: implicit declaration of function `int system(…)'

I've used the system command before and I don't know what's wrong with it, any help will be appreciated very much.

Don't put the int in front of it… You only need to do that when you're making your own function.

I'm not, that's the error I'm putting:

system("mkdir Folder1");

Have you included windows.h?

Yeah, I tried with and without… don't work.

DarkPanther

Oh, I got it to work :)

#include<string>

I really really didn't think you needed that to use system

Oh well hehe

DarkPanther

You don't… technically, it should compile without like all header files, but it's usually standard to include <cstdlib>.

Care to explain ? Im new to C++ started about a week ago.

DarkPanther

Well, most compilers (that I've used anyways) still provide the system() command without ever having to include any header file besides <iostream>. The header file you included should not have affected it all seeing as the <cstdlib> header file handles process control as well as others, which means it is responsible for the system() command. As for system_meltdown's suggestion, well we all know he means well, but in the end it is practically useless and would just bloat your program with an un-needed inclusion.

windows.h is for C, I think C++ is just #include<windows> im not sure though.

You can use either. or even #include<windows.h>
