I was a freshman in C, now the sophomore opened C + +. So we started to start with C + +. So in the beginning there is no indifferent basic summary. The direct transition from C to C + +.First, the preliminary understanding of C + +1. In C,

C + + can define constants with const, or you can define constants in # #, but the former is a bit more than the latter:(1) const constants have data types, and macro constants do not have data types. The compiler can perform type safety checks on

The following three scenarios require the use of the Initialize member list:First, the data member that needs to be initialized is the case of the object;Second, the class member that initializes the const modifier is required;Third, you need to
