uva 10370 Above Average

算出全部的平均，再看有幾個人在平均以上，最後算出百分比。


#include <stdio.h>
#include <stdlib.h>

int main(void){
    int amount,people,i;
    int score[1001],counter;
    double average,percent;

    scanf("%d",&amount);
    while(amount--){
        scanf("%d",&people);

        average=0;
        for(i=0;i<people;i++){
            scanf("%d",&score[i]);
            average+=score[i];
        }
        average/=people;

        counter=0;
        for(i=0;i<people;i++){
            if(score[i] > average) ++counter;
        }

        percent=((double)counter/people)*100;

        printf("%.3lf%%\n",percent);
    }


    return 0;
}
