No.10 while语句统计体重

#include "stdio.h"
#include "stdlib.h"
void main()
{int n=0;
float min=50,max=0,weight,sum=0,ave;
printf("Input weight:\n");
scanf("%f",&weight);
while(weight>0)
{n++;
sum+=weight;
if(weight>max)
max=weight;
else if(weight<min)

printf("Input weight:\n");
scanf("%f",&weight);
}
if(n>0)

ave=sum/n;
printf("Max is:%f\n",max);
printf("Min is:%f\n",min);
printf("Ave is:%f\n",ave);

注意：do,while和whlie{}的区别；注意不要把else写成了esle；注意if, else if, else if, else，若写成if,,if,,,if,,,else是错误的。
