想实现由大到小排序没实现

Question

#include<stdio.h>
int main()
{
struct student
{
long number;
char name[20];
int score;
}a[4]={{10,"liaoaunt",89},{33,"dd",90},{83,"ag",78},{03,"pd",60}};
int k,j,i;
struct student temp;
for(i=0;i<3;i++)
{
k=i;
for(j=i+1;j<4;j++)
{
if(a[i].score<a[j].score)
k=j;
temp=a[i];
a[i]=a[j];
a[j]=temp;
}

}
printf("Number\tName\tscore\n");
for(i=0;i<4;i++)
printf("%d\t%s\t%d\n",a[i].number,a[i].name,a[i].score);
return 0;
}
结果:
Number Name score
3 pd 60
83 ag 78
33 dd 90
10 liaoaunt 89
请按任意键继续. . .
