Casting int to bool in C/C++ - Stack Overflow
Web2.静态下行转换( static downcast) 不执行类型安全检查。 Note: If new-type is a reference to some class D and expression is an lvalue of its non-virtual base B, or new-type is a pointer to some complete class D and expression is a prvalue pointer to its non-virtual base B, static_cast performs a downcast. (This downcast is ill-formed if B is ambiguous, … I know that in C and C++, when casting bools to ints, (int)true == 1 and (int)false == 0. I'm wondering about casting in the reverse direction...

What do the C and C++ standards say about ...
