C++

The previous two blogs have restricted the use of C-language knowledge to a general array, but if you have a complete understanding of the C language, using structures and lists will make the structure of the program clearer and more logical. This

#include using namespacestd;classA { Public: voidasd () {pri (); }Private: /*Virtual*/ voidpri () {cout"base class Functions"Endl; }};classD | PublicA {Private: voidPRI ()/*Override*/{cout"derived class functions"Endl; }};intMainvoid) {B k;

The inheritance protection level of the 1.c++ is best shown to be written out. (Note: The default inheritance for class is Private,struct's default inheritance is public).Cases:Class base{/**/};struct d1:base{/**/}; Default is PublicClass d2:base{/**

1. Assignment statement, assignment statement assigns the value to the storage unit carrots=23. Symbol = is called a copy operation, such as the following codeint Steinway;int Baldwin;int Yamaha;yamaha=baldwin=steinway=77;Assignment will proceed

Take an example of an array of student information structures.#include #include #include using namespace Std;struct student{Publicint n;//No.Char name[20];//nameint age;//Age};int main () {const int n=3;Student A[n];Enter each student information

The so-called macro is a preprocessing command, what is the deal with it? The necessary conversion processing for the program code before the compilation process. Macros have two functions:1. The program only needs to change one place when it

1. The function body is the computer instruction of what the function should do.2. In the C language, each complete instruction becomes a statement.3. The statement ends with a semicolon, and you should not omit the semicolon when you enter the code.
