An enum provides a base class for an enumeration whose underlying type can be any integral type except Char. If you do not explicitly declare an underlying type, use Int32. Programming languages typically provide syntax to declare enumerations that

C + + because the base-class pointers can point to different derived class objects, you should be aware of the memory deallocation of the previous derived class object when assigning different addresses to the base class pointers. int main ()

Both Java and C + + are object-oriented languages. In other words, they are capable of implementing object-oriented thinking (encapsulation, multiplication, polymorphism). And because C + + in order to take care of a large number of C-language users,

When writing programs in C, we often encounter a situation where we want to define a global variable in the header file and then include it in two different C files, which we hope will be shared among two files .For example, there are three files

Header file #ifndef _list_h#define _list_h#includeusing namespace Std;templateclass LIST; Templateclass listnode{friend class list;p ublic:listnode ():d ATA (Type ()), Next (NULL) {} ListNode (Type d, listnode *n = NULL):d ata (d), Next (n)
