C # access private members of similar instances Code As we all know, a private member of a class can only be accessed within it! But I don't know if you have noticed that, in fact, a class instance in C # can access the private members of another

When using the template, remember that typename and class are used as parameters. It's amazing to see it again. Template parameters are not limited to types. You can use built-in types in the compiler. The template tells the compiler that some

1 sizeof is not a function, but an operator.   2. When parsing, the compiler ignores the type name, And the const is near to the person Who modifies the person. Const int * P; // P variable. The object pointed to by P cannot be changed. Int

In some large projects, there may be dozens of basic classes, which are inevitably referenced by each other (not satisfying the inheritance relationship, but composite relationship ). That is, mutual declarations are required. Well, this will bring

More efficient C ++ introduces the differences between pointers and references: Pointers and references look completely different (pointers use operators '*' and '->', and references use operators '.'), but they seem to have the same functionality.

C ++ has three types of members: public members, Private Members, and protected members.If this parameter is not specified, all the Members in the class are public and do not need to be declared. However, private members must be declared. The
