Generate two-bit random integers, random arithmetic characters, and produce 30-word arithmetic questions.First, the idea of programmingTo see the requirements, the first thought is how to use random numbers, because they are not skilled in random

A function overload of a class in Java can be done between functions in this class and from functions in the parent class, and the function overloads in the C + + class can only be in this class (that is, they do not include functions from the

In summary, there are three types of annotations: 1. Single-line Comment 1: //haha single-line comment2. Multi-line annotations 1: /* 2: asdfasdfasdfasdfasdf 3: * /Where multiple lines of comments are written 1: /* 2: *

Constructors are the key to implementing inheritance, when a subclass object is constructed, the constructor of the parent class is called first, and its own constructor is called.#include using namespace std;template class a{public :

Multi-threaded execution methods cannot call the secondary method when the method is not finished executing.It takes a minute to execute a method in a loop, and no member can call the method again within a minute.classMonitorsample {Private intn =1;/

1, New/delete is the operator of C + +, and Malloc/free is a function in C.2, new do two things, one is to allocate memory, and the other is to call the class constructor; Similarly, delete invokes the destructor of the class and frees memory.

When declaring a member function, the const keyword is used to indicate that the function is a "read-only (read-only)" function, which means that the function does not modify any data member (object). To declare a const member function, place the

Java is a strongly typed language, so-called strongly typed, which means that each variable must have a definite type, and each expression must have an explicit type, including some parameters passed. There are two big data types in Java, namely the

interfaces can also be inherited a bit similar to the class, the interface is mainly to supplement some of the public properties can not be inherited by the class, for example: dolphins, not fish, have a lot of fish in common, you can encapsulate

Property declarationpublic int Age {get; set;}Functionally equivalent toprivate int m_age;public int Age {get {return m_age;}set {m_age = value;}Here, there is little difference between a property and a member variable. Equivalent to public int age;

[] is for a specific type, fixed length.List is for a specific type, any length.The Array is for a specific type, fixed length.The ArrayList is for any type, any length.Arrays and ArrayList are implemented in any type by storing object, so they

Static constructors are used to initialize any static data, or to perform specific operations that need to be performed only once. The static constructor is called automatically before the first instance is created or any static members are
