告诉我下列代码如何修改#pragma once#includeiostream#includestringhusing namespace std;enum CPU_Rank P1 = 1 P2 P3 P4 P5 P6 P7 ;class CPU private CPU_Rank rank; int CPU_frequency; double CPU_voltage;public CPUint

代码存在一些问题：

1. 构造函数的参数顺序与初始化列表中的顺序不一致，需要统一。
2. RAM类中的名称属性使用的是string类型，但是默认构造函数中初始化为0，应该改为初始化为空字符串。
3. CDROM类中的名称属性使用的是string类型，但是默认构造函数中初始化为0，应该改为初始化为空字符串。
4. Computer类中的构造函数参数顺序与调用时的顺序不一致，需要统一。
5. Computer类中的output1()函数中的cout语句不够清晰，应该加上更明确的提示信息。

下面是修改后的代码：

#include #include using namespace std;

enum CPU_Rank { P1 = 1, P2, P3, P4, P5, P6, P7 };

class CPU { private: CPU_Rank rank; int CPU_frequency; double CPU_voltage; public: CPU(int newRank, int newFrequency, int newVoltage) :rank((CPU_Rank)newRank), CPU_frequency(newFrequency), CPU_voltage(newVoltage) {} CPU(int newFrequency) :CPU_frequency(newFrequency) {} ~CPU() { cout << "Good bye!" << endl; } CPU(const CPU& p) :rank(p.rank), CPU_frequency(p.CPU_frequency), CPU_voltage(p.CPU_voltage) {} CPU_Rank outRank() { return rank; } int outF() { return CPU_frequency; } double outV() { return CPU_voltage; } };

class RAM { private: string name; int RAM_frequency; int RAM_capacity; public: RAM() :name(""), RAM_frequency(0), RAM_capacity(0) {} RAM(string Name, int a, int b) :name(Name), RAM_frequency(a), RAM_capacity(b) {} RAM(int a) :RAM_capacity(a) {} ~RAM() { cout << "Good bye!" << endl; } string Pname() { return name; } int P_ram_frequency() { return RAM_frequency; } int P_ram_capacity() { return RAM_capacity; } };

class CDROM { private: string Cname; int speed; public: CDROM() :Cname(""), speed(0) {} CDROM(string CName, int Cspeed) :Cname(CName), speed(Cspeed) {} CDROM(string M) :Cname(M) {} ~CDROM() { cout << "Good bye!" << endl; } string P_Cname() { return Cname; } int Pspeed() { return speed; } };

class Computer :public CPU, public RAM, public CDROM { public: Computer(int rank, int frequency, int voltage, string* name, int ram_frequency, int ram_capacity, string* cname, int speed) : CPU(rank, frequency, voltage), RAM(*name, ram_frequency, ram_capacity), CDROM(cname, speed) {} Computer(int ram_capacity, int cpu_frequency, string cname) :CPU(cpu_frequency), RAM(ram_capacity), CDROM(*cname) {} void run() { cout << "Computer开始运行！" << endl; } void stop() { cout << "Computer停止运行！" << endl; } void output1() { cout << "这是一台组装机：" << endl; cout << "CPU:" << endl; cout << "等级：" << outRank() << endl << "频率：" << outF() << endl << "电压：" << outV() << endl; cout << "RAM:" << endl; cout << "品牌：" << Pname() << endl << "主频：" << P_ram_frequency() << endl << "容量：" << P_ram_capacity() << endl; cout << "CDROM:" << endl; cout << "品牌：" << P_Cname() << endl << "传输速率：" << Pspeed() << endl; } };

int main() { cout << "请按顺序输入一台组装机芯片（等级、频率、电压）、内存（品牌、主频、容量）、光驱参数（品牌、传输速率）：" << endl; int newrank, newfrequency, newvoltage; cin >> newrank >> newfrequency >> newvoltage;

string name;
int RAM_frequency, RAM_capacity;
cin >> name >> RAM_frequency >> RAM_capacity;

string Cname;
int Cspeed;
cin >> Cname >> Cspeed;

Computer A(newrank, newfrequency, newvoltage, &name, RAM_frequency, RAM_capacity, &Cname, Cspeed);
A.run();
A.output1();
A.stop();

cout << "请按顺序输入一台品牌机内存大小、CPU的主频、光驱品牌：" << endl;
int ram_capacity, cpu_frequency;
string cname2;
cin >> ram_capacity >> cpu_frequency >> cname2;
Computer B(ram_capacity, cpu_frequency, &cname2);

return 0;
