I have compiled a list of famous and widely used applications and software packages written in C or C++ programming languages. Applications written in both C and C++ programming languages are included due to the fact that most of the applications are partially or completely written in either C language or C++.

These applications are mainly, but not limited to, operating systems, new programming languages, Graphical User Interfaces (GUI) and Integrated Development (IDE) are written in C/C++. The operating systems include Windows 95, 98, 2000, XP, Apple OS X, Symbian OS and BeOS.

Applications written in C/C++

Adobe Applications

Most of the major applications of adobe systems are developed in C++ programming language.

These applications include Adobe Photoshop and Image Ready, Illustrator and Adobe Premier. Adobe has released a lot of open-source code in the past, always in C++, and their developers have been active in the C++ community.
