C header files in linux

[Imin]

hi

if we've been using <iostream.h> in windows, do we use the same header file if we are to program in linux using gcc?

thanx a lot

You should be using <iostream> in both windows and linux. iostream.h will give you warnings in linux and i'm not sure, but i think it'll give you either warnings or errors in newer windows compilers. iostream.h will be taken out of gnu gcc in the future, so it's better to use iostream for current and future projects.

same with other headers like algorithm, fstream, vector, ctype, etc.

Standard C++ uses a namespace called 'std' so all the libraries are organized into that logical group.

#include<iostream>

using std::cout;
using std::endl;

int main() {
cout << "Hello World" << endl;
return 0;
}

g++ prog.cpp
./a.out
