About CPP Files

A .cpp file is a source code file that contains program instructions written in the C++ programming language. CPP files typically contain code that defines how a program performs tasks, processes data, interacts with the operating system, or responds to user input. They may include functions, classes, variables, and other C++ statements that developers can open and edit as plain text.

C++ was developed in the 1970s as an extension of the C programming language and became widely used for developing applications, games, operating systems, and other software. Developers use CPP files with C++ compilers and development environments to create programs for platforms such as Windows, macOS, and Linux, as well as embedded systems and other devices. You may encounter .cpp files when developing software, maintaining existing applications, working with open-source projects, studying programming, or examining the source code for a C++ program.

You can open and view the contents of a .cpp file with a source code editor or plain text editor. However, to compile the code into a program, you generally need a compatible C++ compiler or development environment.
