怎么用c语言计算平均数

Answer 1

#include<stdio.h>
int main()
{
 double a[10],sum;
 int i;
 for(i=0;i<10;i++)
 {
  scanf("%lf",&a[i]);
  sum+=a[i];
 }
 printf("average=%.2lf.\n",sum/10);
}

Answer 2

#include <stdio.h>
void main()
{
int i=0,m,sum=0;
scanf("%d",&m);
while(m>0)
{
sum=sum+m;
i++;
scanf("%d",&m);
}
sum=sum/i;
printf("平均数为%d",sum);

}

Answer 3

#include<stdio.h>
int main()
{
int number;
int sum=0;
int count=0;
scanf("%d",&number);
while(number!=-1){
sum+=number;
count++;
scanf("%d",&number);
}
printf("%f\n",1.0*sum/count);
}
