Lesson 1: A First Program

In this lesson, we closely analyse the program I copied and pasted in last time. I aim to explain how each element works – at a basic level at least – and why we use it. To finish up, I add a few extra lines to consolidate our new knowledge and introduce one or two additional features.

Source Code

The source code featured in this video was as follows:

#include <iostream>

int main()
{
    // write output to the console
    std::cout << "string literal here";
    std::cout << std::endl;
    std::cout << "Because we're all tired of 'Hello World!'" << std::endl;

    // write some more output
    std::cout << "consectetuer adipiscing elit." << std::endl;
    std::cout << std::endl;
    std::cout << 45 << ", " << 3.14 << "." << std::endl;
    std::cout << 45 << "45" << std::endl;
    std::cout << "this is a string literal" << '!' << std::endl;

    return 0;
