九度教程--------2

九度教程第二题

源代码

#include <stdio.h>
#include <algorithm>
#include <string.h> 
using namespace std;

struct E {

char name[101];

int age;

int score; 

bool operator < (const E &b) const{

if(score != b.score)  return score < b.score;

int tmp = strcmp(name,b.name);

if(tmp != 0)  return tmp < 0;

else return age < b.age; 

} 
}buf[1000];

/*
bool cmp(E a,E b){

if(a.score != b.score)  return a.score < b.score;

int tmp = strcmp(a.name,b.name);

if(tmp != 0)  return tmp < 0;

else return a.age < b.age; 
} */

int main()
{

int n;

while(~scanf("%d",&n))

{

for (int i = 0;i < n;i ++)

scanf("%s%d%d",buf[i].name,&buf[i].age,&buf[i].score);

sort(buf,buf + n); 

for (int i = 0;i < n;i ++)

printf("%s %d %d\n",buf[i].name,buf[i].age,buf[i].score);

} 

return 0; 
}

另一种解题方法（用冒泡方法和快速排序）
