One of the harder concepts in C++ is the concept of pointers. Pointers have everything to do with the very nature of the language: C++ gets you pretty close to the hardware you are working with, and one of the most important parts of that hardware is memory. In this tutorial, you will learn to use pointers to refer to memory addresses.
This episode covers debugging. We will see how an application can be halted at any time or at a specific line and how we can inspect variables to verify that everything works as intended. Debugging can be a complex process but we’ll limit ourselves to the basics of breakpoints and following program flow, while keeping an eye on variables.
In this tutorial, we’re going to look at how you can get the computer to calculate with decimal values (numbers like 3.14, called floats), instead of only integral values (numbers like 3, called integers).
This tutorial is about the condition commands C/C++ has which allow you to make automated decisions in your program. You already used conditions when you did loops (perhaps without realising it), but in this episode we will look at more explicit conditions.
