doing a system call

Hi guys

In a win XP command prompt I can do the following:

copy file1+file2 file3
del file1
del file2

Is there a way that I can do this in c++?

Cheers

Code:

---

#include <cstdlib>
...
system ( "del file1" );

---

You can also create a C-style string and pass it into system ().

Doing that you can get input from a user and format it all into a string and use it as an argument. That way, you can change what needs to be deleted or copied ect...

minor nit: should be

std::system ("del file1");

Are you sure?

I dont think the standard "C" headers are in the std namespace.

They are supposed to be, but they aren't for some compilers (like MSVC++ 6.0).

Ah ok, that explains it. So it varies from compiler to compiler.

I wish compilers would all just get along :p

the standard c headers, ie, <stdlib.h> are outside of a namespace. the C++ "new" standard c headers, ie, <cstdlib> should be in std::

Thanks guys. I'll give this a go.
