c++类的操作 复杂类求解！！！

计算机包含CPU和硬盘。请设计Computer、CPU、Disk类。并满足以下测试
int main()
{
string cpuType, diskType;
double frequency, mount;
cin >> cpuType >> frequency >> diskType >> mount;
CPU cpu(cpuType, frequency);
Disk disk(diskType, mount);
Computer computer(cpu, disk);

computer.Print();
return 0;

}
输入
cpu类型 cpu主频
disk类型 disk容量
输出
见测试样例
样例输入1 复制
i7 2.9
ST 2
样例输出1
The computer has a cpu and a disk.
CPU type: i7, CPU frequency: 2.9 GHz
disk type: ST, disk mount: 2 T
怎么实现这个问题？

 class CPU
{
public:
    CPU();
    CPU(string CpuType,double frequency);
};

class Disk
{
public:
    Disk();
    Disk(string DiskType,double mount);
};

class Computer
{
public:
    Computer();
    Computer(CPU cpu,Disk diks);
};

来一个简单的

 class CPU
{
public:
    CPU() {}
    CPU(string _type, double _frenquency) :cpuType(_type), frenquency(_frenquency) {}
    string gettype(void) { return this->cpuType; }
    double getfreq(void) { return this->frenquency; }
private:
    string cpuType;
    double frenquency;
};

class Disk
{
public:
    Disk() {}
    Disk(string _type, double _mount) :diskType(_type), mount(_mount) {}
    string gettype(void) { return this->diskType; }
    double getmount(void) { return this->mount; }
private:
    string diskType;
    double mount;
};

class Computer
{
public:
    Computer() {}
    Computer(CPU _cpu, Disk _disk) :C_CPU(_cpu), C_Disk(_disk) {}
    void print(void) {
        cout << "The computer has a cpu and a disk." << endl;
        cout << "CPU type : " << C_CPU.gettype() << ", CPU frequency : " << C_CPU.getfreq() << " GHz" << endl;
        cout << "disk type : " << C_Disk.gettype() << ", disk mount : " << C_Disk.getmount() << " T" << endl;
    }
private:
    CPU C_CPU;
    Disk C_Disk;
};
