Starting C++ - 01

To follow this perfectly you need:-

- A C++ Compiler
- Knowledge in programming is useful

Right, lets look at some code:

#include <iostream>

using namespace std;

// this is a comment, this is not read by the compiler.
// namespaces will be explained later.

int main() {

cout << "Hello World!" << endl;

return 0;

}

Okay, now, lets look at it line by line:-

#include <iostream>

Without this line, none of the code would work, this includes the C++ code that makes the C++ program work.

using namespace std;

As the comments below state, namespaces will be done in later articles

int main() {

This line, starts our program.
