C++期末考试2：用指针常量比较大小(完整代码含测试)

大家好，我是执念斩长河。一个普通的学习型学渣，昨天21年12月30日周四进行的C++期末考试，我是1班，隔壁二班的题目是这个，我索性将其做出来，放到博文里，以供大家参考。题目就是：用this指针和const比较三个数大小

用this指针与const比较三个数的大小

1. this用在本类
2. const用在做函数参数修饰
3. 三个大if，每个大if里再来一个if，总共有6个if语句

#include
using namespace std;
class Bi{
private:
    int number;
public:
    Bi(int num1){
        number = num1;
    }
    void Compare(const Bi &bi1,const Bi &bi2){
        if(this->number>bi1.number && this->number>bi2.number)
        {
            if(bi1.number>bi2.number)
            {
                cout << this->number<< " " << bi1.number << " "  << bi2.number;
            }
            else
            {
                cout << this->number << "  "  << bi2.number <<" " <<  bi1.number;
            }
        }else if(bi1.number>bi2.number && bi1.number>this->number)
        {
            if(bi2.number> this->number)
            {
                cout << bi1.number << " " << bi2.number << " " << this->number;
            }
            else
            {
                cout << bi1.number << " " << this->number << " " < this->number && bi2.number>bi1.number)
        {
            if(this->number>bi1.number)
            {
                cout << bi2.number << " " << this->number << " " << bi1.number;
            }
            else
            {
                cout << bi2.number << " " << bi1.number << " " << this->number;
            }
        }
    }

};

int main()
{
    Bi b1(2);
    Bi b2(3);
    Bi b3(4);
    b1.Compare(b2,b3);
    return 0;

}
