New page

==YEY==

So I decided to give OOP (Object Orientated Programming ) a chance. So I started from scratch with C++

==Code==

<source lang="C++">
#include <iostream>

using namespace std;

int main (void){
cout << "Hello world" << endl;
return 0;
}
</source>

Compile in linux with
g++ file.cpp -o helloworld
and run
./helloworld
would output
Hello world

==More details==

The #include <iostream> means include the "input output stream" library which gives us access to the 'cout' function. The namespace thingy is a lil bit more complicated. int main(void) means we're creating the main function with no parameters which will return an integer value ( notice the return 0 ). Cout is the function that outputs hello world on the screen and endl adds a endline character.
