It sounds like you are having a pronlem with Dev-c++. I don't use Devc++
so I can't help you there. I have a gcc compiler for my linux and djgpp to
run in the DOS box. Get the docs for devc++. Here's a simple hellow world
program in c++. I started with c++ then switched to c.
#include <iostream>
the above is a preprocessor directive to include the iostream library and
bring its functions into scope.*/
using namespace std;
/* namespaces are part of C++ OOP. Those in c-prog can help you with that.
The using directive says I am using C++'s standared namespace so I don't
have to always inclde the scoping operator :: */
int main(void)
{
cout<<"hello world\n";
return 0;
}
the directional operator << points to stdout or standard output. Nowadays
the screen. It sounds like you problem is with not knowing how to use
dev-c++ though.
