Function names in C++: Capitalize or not? [closed]

Question

What's the convention for naming functions in C++?

I come from the Java environment so I usually name something like:

myFunction(...) { } 

I've seen mixed code in C++,

myFunction(....) MyFunction(....) Myfunction(....) 

What's the correct way?

Also, is it the same for a class method as well as a non-class method?

Answer 1

Since C++11, you may want to use either snake_case or camelCase for function names.

This is because to make a class work as the range-expression in a range-based for-loop, you have to define functions called begin and end (case-sensitive) for that class.

Consequently, using e.g. PascalCase for function names means you have to break the naming consistency in your project if you ever need to make a class work with the range-based for.
