I’d like to use static_assert in my C++11 project to do some compile time check.
As my understanding, static_assert won’t be executed at runtime, right?
If so, when I compile my project by executing the command about compilation, such as gcc ..., the compiler will build the static_assert into the binary file or the static_assert will be totally ignored, just like a comment?
>Solution :
Is static_assert compiled into the binary file
No.

No, it’s not a comment – the expression is checked, and if the expression is false, then a message is shown. When the expression is not a constant (can’t be computed at compile time) then also a message is shown.
