#include<stdio.h>
double averageScore(double score[], int n);  // score存储分数， n为学员个数 
double maxScore(double score[], int n);
double minScore(double score[], int n); 


int main(){
    double score[3];   // 30个分数
    int n = 3; 
    for (int i = 0; i < 3; i++)
        scanf("%lf", &score[i]);    // 输入30个成绩
    
    printf("平均分：%lf\n", averageScore(score, n));
    printf("最大分数：%lf\n", maxScore(score, n));
    printf("最小分数：%lf\n", minScore(score, n));
}

double averageScore(double score[], int n){
    double sumScore = 0.0;
    for(int i = 0; i < n; i++)
        sumScore += score[i];
        
    return sumScore / n;
}

double maxScore(double score[], int n){
    double maxscore = -1.0;
    for(int i = 0; i < n; i++)
        if (score[i] > maxscore)
            maxscore = score[i];
    
    return maxscore;
}

double minScore(double score[], int n){
    double minscore = 1000.0;
    for(int i = 0; i < n; i++)
        if (score[i] < minscore)
            minscore = score[i];
    
    return minscore;
}
