   水题。。不会函数重载。。写了三个cmp。。

#include <iostream>#include <cstring>#include <cstdio>#include <algorithm>using namespace std;struct type {char name[105];int year;int price;};int cmp1(struct type a,struct type b){if(strcmp(a.name,b.name)==0){if(a.year==b.year)return a.price<b.price;return a.year<b.year;}if(strcmp(a.name,b.name)<0)return 1;return 0;}int cmp2(struct type a,struct type b){if(a.year==b.year){if(strcmp(a.name,b.name)==0)return a.price<b.price;if(strcmp(a.name,b.name)<0)return 1;return 0;}return a.year<b.year;}int cmp3(struct type a,struct type b){if(a.price==b.price){if(strcmp(a.name,b.name)==0)return a.year<b.year;if(strcmp(a.name,b.name)<0)return 1;return 0;}return a.price<b.price;}int main(void){int ncase;char tmp[10];struct type book[105];int blank = 0;while(cin>>ncase && ncase){if(blank++)printf("/n");for(int i=0;i<ncase;i++)cin>>book[i].name>>book[i].year>>book[i].price;cin>>tmp;if(strcmp(tmp,"Name")==0){sort(book,book+ncase,cmp1);}else if(strcmp(tmp,"Year")==0){sort(book,book+ncase,cmp2);}else{sort(book,book+ncase,cmp3);}for(int i=0;i<ncase;i++){cout<<book[i].name<<" "<<book[i].year<<" "<<book[i].price<<endl;}} // cout << "Hello world!" << endl; return 0;}
