Introduction to C++

What is C++?

C++ is a low-level programming language which means that you can do things like directly manipulate memory. C++ is based on the C programming language, except C++ has classes and other things that C does not have.

History

C++ was created by Bjarne Stroustrup as an improved version to C. C++ is quite old compared to other programming languages, being released in 1985.

Uses

C++ is very fast, so it is used in places where speed and efficiency are very important:

Running C++

C++ is a compiled language which means that C++ takes your code and turns it into an executable, which is machine code that your computer can natively understand, no compiler or interpreter needed. Then, we run the executable.

C++ has many compilers, but for this tutorial series we will be using the GCC compiler. Once we install GCC, we can use the g++ command to compile our C++ code.
