问个简单的C语言问题 将三个运动员按成绩由高到低排序，此代码运行的时候11.1后面那些奇怪的东西是什么？

Question

#include <stdio.h>
struct Student
{
int num;
double score;
};
main()
{
struct Student stu[3]={{11,12.4},{95,11.1},{41,13.4}};
struct Student temp;
int i,j;
for(j=0;j<9;j++)
for(i=0;i<9-j;i++)
if(stu[i].score<stu[i+1].score)
{
temp=stu[i];stu[i]=stu[i+1];stu[i+1]=temp;
}
printf("The order is:\n");
for(i=0;i<10;i++)
printf("% d,% g",stu[i].num,stu[i].score);
printf("\n");
return 0;
}
