C and C++ are high-level programming languages that are widely used for developing system software and application software. They were developed to handle a wide variety of applications and meant to be cross platform compatible, so you only have to recompile your code on the new operating system for it to work. Of course, if…
Trying to list the most popular languages can be a real challenge. This is because the popularity of programming languages vary over time and depend on the specific field or application. For example, Python is widely used in fields such as Machine Learning and scientific computing, while JavaScript is one of the core technologies of…
There are many reasons why there are different programming languages. Evolving Technology One of the main reasons is that technology is always evolving, and as more technologies come into being and advance, we need more tools that can make use of these technologies. You might remember from previous classes with me, we’ve talked about how…
This is a problem which might come up during a job interview, to try to figure out, how do you think. And it goes something like: “Can you count (i.e. print each number), from 1 to 100, without using a loop?” Now some languages will have some special functions which you can use to do…
You can extend almost any class you want. So once you’ve defined a base class, you just need to know enough about it, and how you want to derive from it. Considering our GenericGeometric class from before, let’s look at deriving a Circle class from it. In our header file we will have: Notice two…
One of the cool things about object oriented programming is that you can derive a class from an existing class. this allows you to have most of the class built from an existing class, and not need to rewrite the whole class, only the new parts. Additionally, if the original class, called the base class…
We’ve seen how to overload an operator in C++. The stream operators are similar in nature, however, they can be a bit more involved. In many languages, there is a default toString() method for your classes, which lets the language know how to connect to the string. However, there isn’t one in C++, so we…
Not only can you use templates for a primitive data type within functions, but also within classes. Consider the following example: The methods are similar to a non-template class, however, each method is a template itself, so you have to adjust a few things. For example, you have to specify template<typename T> before each method….
