怎末不输出PK结果呢
怎末更改

#include<iostream>
#include<cstring>
using namespace std;
class Songer{
private:
    char name[20];
    long long fans_count;
    const int count;
public:
    Songer(){
        strcpy(name,"");
        fans_count=0;
        count=3;
    }
    songer(const Songer&song){
        strcpy(name,song.name);
        fans_count=song.fans_count;
        count=song.count;
    }
    void read(){
        gets(name);
        int fans;
        cin>>fans;
        fans_count=fans;
    }
    void Set(int num){
        fans_count=num;
    }
    ~Songer(){
        cout<<"执行析构函数"<<endl;
    }
    int show_count(){
        return count;
    }
    friend void PK(Songer &a,Songer &b);
};
 void PK(Songer &a,Songer &b){
        if(a.fans_count>b.fans_count){
            cout<<a.name<<"战胜"<<b.name<<endl;
        }
        if(a.fans_count=a.fans_count){
            cout<<a.name<<"和"<<b.name<<"是平局"<<endl;
        }
        if(b.fans_count<a.fans_count){
            cout<<b.name<<"战胜"<<a.name<<endl;
        }
}
int main(){
    Songer num1,num2,num3;
    num1.read(),num2.read(),num3.read();
    num1.show_count();
    PK(num1,num2);
    PK(num2,num3);
    PK(num3,num1);
    return 0;
}

首先，是a和b比，你两边都是a了，其次==不是=

 void PK(Songer &a,Songer &b){
        if(a.fans_count>b.fans_count){
            cout<<a.name<<"战胜"<<b.name<<endl;
        }
        if(a.fans_count==b.fans_count){
            cout<<a.name<<"和"<<b.name<<"是平局"<<endl;
        }
        if(b.fans_count<b.fans_count){
            cout<<b.name<<"战胜"<<a.name<<endl;
        }
}
