  • 类的组合,注意对对象成员的初始化要用成员初始化列表。
  • 利用拷贝构造函数初始化组合类的时候注意对象成员要有拷贝构造函数,牵扯深拷贝与浅拷贝。
  • 深拷贝与浅拷贝区别:主要体现在使用指针时,深拷贝(自己实现)申请新内存,浅拷贝没有申请新内存。
  • C++多文件操作。
  • 继承开头。

#include "CPU.h"#include "Memory.h"#include
using namespace std;class Computer{ public://在组合类中,成员初始化列表的调用顺序不影响构造函数的调用顺序 Computer(string brand,double fre,int cap):cpu(brand,fre),mem(cap){ //不能在构造函数里面初始化对象成员,用成员初始化列表 cout<<"A computer is created."<
