Alternatives for g++

• Bad idea. Make your life easy, get the same error messages we see.
• If you insist...
• Old g++: ok for now if not too old.
• CLang++: at your own risk. Messages and optimization differ.
• MS Visual C++: no. Too different.

Notes:

g++ 11 is out. 10.something will still do.

Clang++ optimizes more aggressively.

There will be warnings g++ doesn’t emit, as well as no warnings when g++ does warn.

Those who would use MSVC++ just because they fail to install g++ automatically disqualify to use it for the course.
