ARM Tutorial

This is a very short introduction to C++ programming, it assumes a basic knowledge of C.

A First Program

#include < iostream>
using namespace std;

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

This program simply prints out "Anything but Hello World". It is explained below:

# include < iostream> is a preprocessor directive. It tells the preprocessor to include the contents of iostream header file in the program before compilation.
int main() is a function. C++ program is a collection of functions. Every program in C++ begins executing at the function main(). Every C++ program has exactly one main function and a collection of other functions.
