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…
Let’s look a little closer at constructors than we did in our initial Defining Classes for Objects example. Anytime you create an object, a constructor is called. If you overload your constructor, C++ will pick the right constructor to call, just like it does when you overload a function. Constructors must have the same name…
Once you create your class, you need to create an object. The Class is just a blueprint for the program to follow. It doesn’t do anything until you create an object based off of that blueprint. Think of a house. If you have a house blueprint, all you have are some sheets of paper or…
Object Oriented Programming (OOP) involves programming using objects. An Object is made from a Class which defines the attributes of the object and the behaviors. Think about it like what is it about or with adjectives (attributes) and what it can do, or verbs, (behaviors). As an example let’s consider a Class called Student. A…
Multi-dimensional arrays, often called a matrix, are possible in C++. C/C++ treats them as an array of arrays. Because of how they are defined, each array within the array will be of the same size. This actually makes them easier to work with. To define them, you use two sets of brackets, and can think…
A C String is actually an array of characters. While C strings are a thing, generally speaking it is best to use the C++ string object. However, if you run into an older application, or someone who wants to do things old style, it is good to know how to use a C-String. Additionally, any…
Because an array is used to store a collection of data, it is important to know how to use them efficiently. Searching Arrays We often need to search an array to see if a value is inside of it or not. While some languages do this for you, C++, because of it’s age, doesn’t. Linear…
You pass an array to a function, very similarly as to how you would pass a non-array variable. There are two differences. You need to include square brackets after the array name so C++ knows its and array Realize that you are passing by reference. The book recommends that you always pass the size of…
