用 C语言 “数组” 求

#include <stdio.h>

void main()
{
int a[10],i,sum=0;
for (i=0;i<10;i++)
{
printf ("a[%d]= ",i);
scanf ("%d",&a[i]);
}
for (i=0;i<10;i++)
sum+=a[i];
printf ("总分sum= %d\n",sum);
printf ("平均分average=%.4f\n",(float)sum/10);
}

#include <stdio.h>
main()
{
int a[10],i; //定义
double sum=0,avg;
printf("input:");
for(i=0;i<10;i++) //输入
scanf("%d",&a[i]);
for(i=0;i<10;i++） //输出
{printf("%4d",a[i]);sum+=a[i];}//sum存放他们成绩之和
avg=sum/10; //计算平均值
printf("the sum of them is %lf\n",sum);//输出即可
printf("the average of them is %lf\n",avg);
}
