Conversion of C + +

1, Static conversion static_cast

Used for explicitly defined transformations, including non-casts that are allowed by the compiler, and less secure but well-defined transformations. PS: (Non-forced transformations, narrow transformations, implicit conversions, class-level static positioning, void* coercion)

2. Constant conversion const_cast

Used to convert from const or volatile to non-const or non-volatile

3. Re-interpretation conversion reinterpret_cast

Unsafe conversion mechanism

Illusion of objects as completely different types of objects (bitwise operations)

Thought: When you need to use it, what you get is different so that it cannot be used for the purpose of the original type.
