C++学习一 结构与结构体

Posted 2022-12-18 fantianliang

结构体属于C++与C区别之一。

代码例子如下（来自《C++程序设计》）：

#include <iostream>
#include <string>
using namespace std;
//结构体 
struct EnemySpaceShip

    int x_coordinate;
    int y_coordinate;
    int power;
;          //结构体后面始终都要有一个‘;‘ 
//结构体初始化
 EnemySpaceShip getNewEnemy()
 
     EnemySpaceShip ship;
     ship.x_coordinate=0;
     ship.y_coordinate=0;
     ship.power=4;
     return ship;
 
 EnemySpaceShip upgrateWeapons (EnemySpaceShip ship)
 
     ship.power+=10;
     return ship;
     return ship;
 
 
int main()

    EnemySpaceShip enemy=getNewEnemy();
    enemy=upgrateWeapons(enemy);
    enemy=upgrateWeapons(enemy);
    cout<<"the ship is "<<enemy.x_coordinate<<","<<enemy.y_coordinate<<","<<enemy.power<<endl;
