Question

Does anyone know of a tool that I can use to find explicit C-style casts in code? I am refactoring some C++ code and want to replace C-style casts where ever possible.

An example C-style cast would be:

Foo foo = (Foo) bar;

In contrast examples of C++ style casts would be:

Foo foo = static_cast<Foo>(bar);
Foo foo = reinterpret_cast<Foo>(bar);
Foo foo = const_cast<Foo>(bar);

If you’re using gcc/g++, just enable a warning for C-style casts:

g++ -Wold-style-cast ...
