The memory in the computer is the storage space in bytes . Each byte of memory has a unique number, which is called an address . As if the hotel is a room unit, each room has a unique room number, we can find the corresponding room according to room

Do not neglect the compiler's warningsCompiler warnings don't bother some programmers. They believe that warnings do not threaten the program or do not have much of a side effect on the program. However, this idea may cost a great price when it

Two ways of operator overloadingFor many operators, you can choose to use member functions or non-member functions to implement operator overloading. In general, a non-member function should be a friend function so that the private data of the class
