C Code File Extensions: .cc vs. .cpp: Which One Should You Choose?

File Extensions for C Code: .cc vs. .cpp

In the realm of C development, code can be stored in files with either a .cc or .cpp extension. However, it's not immediately clear which one is the preferred or more modern choice.

The Google Style Guide: Advocating for .cc

The Google C Style Guide leans towards the use of .cc file extensions for C source files. This is primarily a stylistic preference, as it helps differentiate C code from C code, which typically uses .c extensions.

Compiler Compatibility: No Preference

It's important to note that C compilers do not distinguish between .cc and .cpp files. They can compile code from either format equally well. Therefore, the choice between the two is purely based on personal preference or team conventions.

No Decisive Edge: A Matter of Choice

Ultimately, the decision between using .cc and .cpp extensions is a matter of personal preference or team policy. While certain style guides may recommend one extension over the other, there is no technical advantage or disadvantage to either format. The choice should be based on what is most consistent and convenient for the development team.

In the specific context of Linux systems, either file extension is equally suitable.
