.cpp — C++ Source Code
Source code written in the C++ programming language, which must be compiled into machine code before it can run.
Also known as: .cc, .cxx, .c++
Safety guidance (not a guarantee)
Source code is plain text and doesn't execute on its own — it has to be compiled or run by a specific tool, which is where any real risk would occur.

Frequently asked questions
What is a .cpp file?
Source code written in the C++ programming language, which must be compiled into machine code before it can run.
Can I edit a .cpp file?
Yes — .cpp files are commonly editable with software such as GCC / Clang.
Does having a .cpp extension mean the file is safe?
No single extension can guarantee that. Source code is plain text and doesn't execute on its own — it has to be compiled or run by a specific tool, which is where any real risk would occur. Always consider where the file came from, not just its name.
