    啊这,如果是比赛的话,肯定就用 sort 函数了。写个 cmp 就随便打。

    #include <iostream>
    #include <algorithm>
    
    using namespace std;
    
    struct node2 {
    	string name;// 姓名
    	int score;// 乘积
    };
    
    bool cmp(node2 a, node2 b) {
    	return a.score > b.score;
    }
    
    
    int main(void) {
    	int N;
    	cin >> N;
    
    	node2* arr = new node2[N];
    
    	for (int i = 0; i < N; ++i) {
    		string name;
    		int score;
    		cin >> arr[i].name >> arr[i].score;
    	}
    
    	sort(arr,arr+N,cmp);
    	
    	for (int i = 0; i < N; ++i) {
    		string str = "";
    		int score = arr[i].score;
    		if (score == 0) {
    			str = "Bad";
    		}else if (score >= 1 && score < 200) {
    			str = "Not good";
    		}else if (score >= 200 && score < 300) {
    			str = "Bronze medal";
    		}else if (score >= 300 && score < 400) {
    			str = "Silver medal";
    		}else if (score >= 400) {
    			str = "Gold medal";
    		}
    
    		cout << arr[i].name << " " << arr[i].score << " " << str << endl;
    	}
    
    
    	return 0;
    }

      思路:

      结构体存名字和成绩,然后sort成绩从大到小(cmp函数),对应输出就行

      #include<bits/stdc++.h>
      using namespace std;
      struct stu{
      	int num;
      	char name[25];
      }st[300];
      bool cmp(stu x,stu y){
      	return x.num>y.num;
      }
      int main()
      {
      	int n;
      	scanf("%d",&n);
      	for(int i=0;i<n;i++)
      	{
      		scanf("%s",st[i].name);
      		scanf("%d",&st[i].num);
      	}
      	sort(st,st+n,cmp);
      	for(int i=0;i<n;i++)
      	{
      		printf("%s ",st[i].name);
      		if(st[i].num==0)printf("%d Bad\n",st[i].num);
      		else if(st[i].num>=1&&st[i].num<200)printf("%d Not good\n",st[i].num);
      		else if(st[i].num>=200&&st[i].num<300)printf("%d Bronze medal\n",st[i].num);
      		else if(st[i].num>=300&&st[i].num<400)printf("%d Silver medal\n",st[i].num);
      		else printf("%d Gold medal\n",st[i].num);
      	}
      	return 0;
      }

            这道题我wa了好多好多次,原因是用了c++里面的std::ios::sync_with_stdio(false)。(说实话,我不知道为啥会错) 然后思路就是结构体加排序,直接做就行。

              题解

              这个题用结构体储存每个同学的名字和成绩,然后根据每位同学的成绩进行排序(比如sort排序,cmp大法),最后根据每位同学的分数判断奖项进行输出即可,上代码:

              代码

              #include<bits/stdc++.h>
              #include<iostream>

                  还好的一道题,但是要注意题目要求,不要看到前面都是100进就直接以为BAD是0到100了(我死在这上面了)用sort排序时也要注意题目要求

                    总的来说,这道题挺简单的,但是Wrong了很多次,事实证明对map的理解还不够,最开始用map来做的,又忽视了题意中的如果总成绩相等,按输入顺序排序

                      题目解析: 本题是一个很明显的结构体排序,由于数据较小,冒泡排序应该也可以,不过一般是用sort快捷完成排序。构建结构体Person,内含成员姓名,成绩和获得的奖项,由于是根据成绩由大到小排序,需要改写一下cmp,最后就是简单的if判断了,注意赋值给奖项时,如果使用的是字符数组,要用strcpy来赋值,如果是string类直接赋值就行了。

                      可行代码:

                      #include <bits/stdc++.h>
                      using namespace std;

                      	string get;
                      }Person;
                      Person a[500];
                      bool cmp(Person a, Person b) {
                      	return a.score > b.score;
                      }
                       
                      int main(){
