在一個長度為10的整型數組里面，保存了班級10個學生的考試成績。要求編寫5個函數，分別實現計算考試的總分，最高分，最低分，平均分和考試成績降序排序。
#include <stdio.h>
int main()
{
int score[]={67,98,75,63,82,79,81,91,66,84};
int num;
int all;
int i;
int j;
int qw;
for(num=0,all=0;num<10;num++)
{
all+=score[num];
}
printf("這次考試十個學生的總分是%d。\n",all);
printf("這次考試的平均分是%.1f。\n",all/10.0);
for(qw=0;qw<=10;qw++)
{
for(j=0;j<=9;)
{
if(score[j]<score[j+1])
{
i=score[j+1];
score[j+1]=score[j];
score[j]=i;

j+=1;

printf("這次考試按排名排是 ");
for(i=0;i<=9;i++)

printf("第%d名：%d分。",i+1,score[i]);
}
return 0;
