You don't have linters for C/C++ as far as I know. I guess they could have included code-formatters too, like clang-format.

cpplint?
Of course C was a different languange back then. But I am rather sure modern variants exist.
Clang-tidy comes to my mind, but I don't write any significant amount of C/C++ these days.
