结构体数组的应用举例 例9-4 L9-4 有n个学生的信息（包括学号，姓名，成绩）要求按照成绩的高低顺序输出各学生的信息

#include
typedef struct Struct
{
	int num;
	char name[20];
	float score;
}student;

int main(void)
{
	student stu[5]={{10101,"Zhang",78},{10103,"Wang",98.5},{10106,"Li",86},{10108,"Ling",73.5},{10110,"Sun",100}};
	student temp;
	const int n=5;
	int i,j,k;
	printf("The order is:n");
	for(i=0;istu[k].score)
				k=j; 
		}
		temp = stu[k];
		stu[k]=stu[i];
		stu[i]=temp;
	}
	
	for(i=0;i
