学习c语言时的一些例程

#include<stdio.h>
void main()
{float score[4],ave,sum=0,x;
int i,n=0,count;
printf("\nInput a number:");
scanf("%f",&x);
while(x>=0&&n<4)
{sum+=x;
score[n++]=x;
scanf("\nInput a number:%f",&x);
}
ave=sum/n;
printf("\nAverage=%f",ave);
for(count=0,i=0;i<n;i++)
if(score[i]>ave)
{printf("%f\n",score[i]);
count++;
if(count%2==0) printf("\n");
}
printf("\ncount=%d",count);
}
