When you write functions in C++, you often have to pass the same values over and over again. If you are making a tool to figure out how big a rectangle is, for instance, you might normally use a standard height but variable widths. Instead of typing the height every single time, C++ allows you …
In traditional programming, code usually runs in a straight line from the top to the bottom. But logic in the actual world is rarely that straightforward. Think of a game where you can only get a “Life Up” if your score is over 1000, or a banking software that only lets you take out money …
When you write a program in C++, you are essentially having a conversation with the computer. To make sure the computer understands you, the language uses a specific set of “reserved words” known as C++ keywords. These are the “VIPs” of the language, they have special jobs that no other word can do. For example, …
Memory in C++ is like a big library where each piece of data has its own “address,” which is like a unique seat number. We usually use variable names to find our data, but sometimes we need to be more particular. This is when pointers and references in C++ come in handy. You may use …
When writing code, errors are inevitable. Sometimes a file might be missing, or a calculation might result in a division by zero. In C++, we employ exceptions to deal with these “surprises.” But have you ever thought about what happens to the variables and objects that were in use when an error happened? This is …
