All of the modern compilers can detect issues which are not errors, by enabling high warning settings. In the video, Troy explains how to enable a higher warning level and what the results will be.
- [Instructor] C++ is hard,…and the compiler knows the language better than you do.…Let the compiler help you.…Turn on all warnings that make sense.…I would also advise not letting warnings go.…Often, a warning is actually a bug.…Here are a few compiler warning flags…that I like and I hope you do too.…For GCC and Clang, the options are the same.…Dash wall disenables all the warnings.…Dash Wextra disables some extra warnings…that are not enabled by dash W all.…
Dash Wpedantic issues all warnings…demanded by strict ISO C and C++.…Dash Wunused warns about unused type definitions.…For Microsoft, forward slash W4 is all reasonable warnings.…Forward slash 14640 is about thread unsafe…static members initialization.…I would highly suggest that you take a look…at the compiler's website to see if there are others…that are a good fit for your development.…
