c++ - What happened to std::assert

Question

This answer and it's multitude of duplicates indicate that I should be using #include <c*> for the C headers that I pull from in C++ code, and that I should be calling them with std::*.

I have been doing that but I notice an exception. std::assert doesn't seem to be defined, even when I correctly #include <cassert>.

What's going on here? Is this an implementation oversight, or an actual exception?

Answer 1

assert is a macro, not a function. Hence, it needs to be used with plain old assert(condition).
