下面的程序先输入10位同学的成绩，求平均分，再求低于平均分的人数，最后输出
#include<stdio.h>
#include<stdlib.h>
int main()
{
int grade[10];
int i;
double ave;
int sum;
int sign;
for(i=0;i<10;i++)
{
printf("please input %d grade:
",i+1);
scanf("%d",&grade[i]);
}
printf("the grades are:
");
for(i=0;i<10;i++)
{
printf("%d ",grade[i]);
}
sum=0;
for(i=0;i<10;i++)
{
sum=sum+grade[i];
}
ave=sum/(1.0*10);
printf("
the average grade is:%f
",ave);
printf("the numbers of students below the average grade:
");
//printf("the number is:%d
",(int)ave);
sign=0;
for(i=0;i<10;i++)
{
if(grade[i]<(int)ave+1)
{
sign++;
}
}
printf("%d
",sign);
return 0;
}
运行结果如下，如果有什么不明白的还可以问我
