    {
        if(a[i]>average)
        printf("%0.2f\t",a[i]);
    }

scanf("%d",&a[i]);

还是不行

%d,%f,看看数据类型要匹配，要用float型printf("%0.2f\t",a[i]);……printf("%.2f\t",a[i]);

还是不行,输出不了要的结果

#include <stdio.h>
int main()
{
    float a[10],high,average,sum;
    int i;
    printf("Enter 10 students's score: ");
    for(i=0;i<10;i++)
    {
        scanf("%f",&a[i]);
    }
    
    high=a[0];
    sum=a[0];
    for(i=0;i<10;i++)
    {
        sum=sum+a[i];
        if(a[i]>high)
        high=a[i];
        
    }
    average=sum/10;
    for(i=0;i<10;i++)
    {
        if(a[i]>average)
        printf("%g\t",a[i]);
    }
    return 0;
   }

好了,谢啦
