If you code in C++ you have probably used the internal speaker for some quick debug of your programs, in Windows, we can use the winapi header (windows.h) to access the built in function Beep(): Beep(frequency,duration); Where frequency is in Hertz and duration in milliseconds. So here is a quick something I did on C++ [...]

What functions are faster? Which ones are the most efficient? Understanding this will help you optimise your code and impove it’s performance. Each C++ function has a run time, and knowing that will allow you to combine the best methods always. Here you have the different possible run times, explained and with an example of [...]

In C++ we have what’s called the Standard Template Library (STL) which provides a lot of useful shortcut functions that will help us develop our code. Today I wanted to show you the basics of the vector library. How arrays will go from being a nightmare to the easiest thing ever in our C++ applications. [...]

I don’t know whether this is useful or merely entertaining, but it is quite simple to display the character representation of any ASCII number in C++ We will use the static_cast function to perform this operation, converting from int to char. Let me show you this sample program that does just that (Looping until you [...]

As you might know, when we develop a simple program that runs in the system console, using the standard library iostream, we might want to have special ways of displaying a class object. You have probably heard of the istream and ostream operators (<< and >>), we can use overloading to change their behaviour. Since [...]
