奖学金(结构体实在是太好用啦）

解题思路:

注意事项:

注意只有前五名才有奖学金
参考代码:

#include<stdio.h>
struct student 
{
    int sno;
    int Chinese;
    int math;
    int English;
    int sum;
};
int main()
{
	int n;
	scanf("%d",&n);
	struct student grade[n];
	for(int i=0;i<n;i++)
	{
	    grade[i].sno=i+1;
	    scanf("%d%d%d",&grade[i].Chinese,&grade[i].math,&grade[i].English);
	    grade[i].sum=grade[i].Chinese+grade[i].math+grade[i].English;
	}
	for(int i=0;i<n;i++)
	{
	    for(int j=i+1;j<n;j++)
	    {
	        struct student a;//结构体变量
	        if(grade[i].sum<grade[j].sum)//总分比较
	        {
	            a=grade[i];
	            grade[i]=grade[j];
	            grade[j]=a;
	        }
	        else if(grade[i].sum==grade[j].sum)//总分相等时
	        {
	            if(grade[i].Chinese<grade[j].Chinese)
	            {
	                a=grade[i];
	                grade[i]=grade[j];
	                grade[j]=a;
	            }
	            else if(grade[i].Chinese==grade[j].Chinese)//语文成绩相等时
	            {
	                if(grade[i].sno>grade[j].sno)
	                {
	                    a=grade[i];
	                    grade[i]=grade[j];
	                    grade[j]=a;
	                }
	            }
	        }
	    }
	}
	for(int i=0;i<5;i++)//注意阿，只有前五名才能获得奖学金
	{
	    printf("%d %d\n",grade[i].sno,grade[i].sum);
	}
	return 0;
}
