Our "Try it Yourself" editor makes it easy to learn C++. You can edit C++ code and view the result in your browser.
C++ is an object-oriented programming language which gives a clear structure to programs and allows code to be reused, lowering development costs. C++ is portable and can be used to develop applications that can be adapted to multiple platforms.
To start using C++, you need two things: A text editor, like Notepad, to write C++ code. A compiler, like GCC, to translate the C++ code into a language that the computer will understand. There are many text editors and compilers to choose from. In this tutorial, we will use an IDE (see below).
C++ Classes/Objects. Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, Python, PHP, Bootstrap, Java, XML and more.
OOP stands for Object-Oriented Programming. Procedural programming is about writing procedures or functions that perform operations on the data, while object-oriented programming is about creating objects that contain both data and functions.
We have gathered a variety of C++ exercises (with answers) for each C++ Chapter. Try to solve an exercise by editing some code, or show the answer to see what you've done wrong.
Comments can be used to explain C++ code, and to make it more readable. It can also be used to prevent execution when testing alternative code. Comments can be singled-lined or multi-lined.
C++ Switch Statements. Use the switch statement to select one of many code blocks to be executed.
Variables are containers for storing data values. In C++, there are different types of variables (defined with different keywords), for example: char - stores single characters, such as 'a' or 'B'. Char values are surrounded by single quotes. string - stores text, such as "Hello World".
A function is a block of code which only runs when it is called. You can pass data, known as parameters, into a function. Functions are used to perform certain actions, and they are important for reusing code: Define the code once, and use it many times.
