Static variables of C + + are divided into static global variables and static local variables. Static variables are stored in a static code area, are members of the class level, exist as any object that takes precedence over the class, and are

　　In C + +, theconst modifier is typically used to modify constants. Constants must be initialized at the time of definition and cannot be modified once the value is defined, thus guaranteeing that the value of the constant will not change during

There are roughly three return values in C + +: value copies (replicas), value references, and pointers, and what type of values to return depends on the situation.If you return a copy of a large object, it is a time-consuming process to return

The nature of the AVL tree1. The absolute value of the difference between the height of the right subtree of the Saozi does not exceed 12. Each Saozi right subtree in the tree is an AVL tree3. Each node has a balance factor (balance FACTOR--BF), and

When an object in the queue has a higher priority than other objects, it needs to use a priority queue before other objects are first out of the queue regardless of where they are located.Like the next implementation method-Insert at the end of the

Item M20: Assist to complete return value optimizationa function that returns an object is difficult to be efficient, because the return of a value results in the construction and destructor within the calling object (see clause M19), which cannot

--Exception captureWe often have a variety of anomalies in the program, if you want your program to become stronger.You should use Try-catch frequently for exception trapping in your code.try{ //可能会出现异常的代码;}catch(Exception ex){ //Exception
