Enum enum is the keyword in both C + + and Java, but they are not the same. For C + +, enumerations are a series of named Integer constants, and conversion from enumeration values to corresponding integer values is done internally. For Java,

Transferred from: http://blog.csdn.net/chgaowei/article/details/6427731To support the polymorphism of C + +, dynamic binding and static binding are used. Understanding their differences can help to better understand polymorphism and avoid making

Summary: C + + is a programming language developed on the basis of C language, which integrates object-oriented programming, generic programming and procedural programming. Widely used, it is a kind of static data type checking, and supports

For classes and class inheritance, there are several main issues:1) Inheritance mode: Public/protected/private inheritance.This is a C + +, in fact, inheritance is a kind of permission to allow sub-class control ideas. The subclass inherits from

(i) the meaning of voidVoid literally means "no type", and void is almost only "annotated" and restricts the function of the program, since no one will ever define a void variable, let's try to define:void A;This line of statement compiles with an

Recommendation 22: Ensure thread safety for collectionsCollection thread security is when elements are added or removed on multiple threads, and the line Cheng must be kept in sync.The following code simulates one thread during the iteration, and

Summarypointers can point to variables, arrays, strings, functions, and even structs. That is, pointers can point to different data objects. Pointer problems include constant pointers, array pointers, function pointers, this pointer, pointer passing

Sequential containers::(vectors and lists and deque)The erase iterator not only invalidates all iterators that point to the deleted element, but also invalidates all iterators after the deleted element, so erase (iter++) cannot be used, but the
