Article 7: implement the value type as constant and atomic as much as possible. Constant-it remains unchanged after being created and cannot be modified; thread security.We need to pay attention to the variable reference type field in the constant

1. Introduce STL and explain in detail how STL implements vector. 4. What are the differences between pointer and reference? If it is safer to pass a reference than to pass a pointer, why? Isn't it true if I use a constant pointer? 5. There are

Document directory Copy constructor Destructor Copy constructor ):A special constructor with a single parameter, which is a reference to this type. When you define a new object and initialize it with an object of the same type, the copy

We strongly recommend that you use the unsigned type when using the bitvector operator. Because the signed type has different implementations on different machines, the Code may become unavailable!   Bitwise inversion, bitwise OR, or bitwise AND
