Templates are like a way to simplify making overloaded functions, by allowing for a function with generic data types to be written, to have the compiler change at compile time. The Generic Version of this would look like: Think of something like where you want to determine the max value of two variables. Well, you…
We’ve talked about Constructors in C++ already. One of the special methods, along with Destructors, that C++ offers. There is a third, special method which C++ offers. That is called a Copy Constructor. The Copy Constructor is a special type of constructor, which is intended for use when you duplicate an object. Some people will…
We’ve looked at Constructors in C++ to create an object, and building an object with new. However, what happens when we no longer need that object? That’s where a destructor is called. It is built into all objects, and if you don’t define one, a default one will be called for you. The destructor’s job…
While you can create pointers with ordinary primitive objects, that’s not where the real power of pointers lie. The power is to reference objects that we create, so they don’t take up too much space in lower memory locations, and we can work on passing them around. To create an object dynamically on the heap,…
C++ has some interesting keywords that allow you to do different things. For example, if you want to make sure that you don’t accidentally change any values in a method, you can use the const keyword. Now this is similar to how you use it on a parameter for a function, but since you don’t…
Something that can happen in larger projects is that a header file for a class is included in multiple files. While this seems trivial, some compilers can run into a problem of thinking it’s multiple classes with the same name. Luckily, C++ gives us a method to prevent this from happening, by using a built…
Everything we’ve looked at so far is what is known as an instance member. That is, each instance of a class – called and object, has it’s own set of properties and methods. This is mostly what is done. So if we look at two Circle objects for example, the radius of one circle is…
Large projects may be written by multiple people, or even companies being contracted. Medium projects may not want to have a single large file, and instead, break it into smaller chunks, or files, which makes managing the project easier and easier to edit the files as you look for items. To do this, you need…
