c语言统计学生成绩函数

在C语言中，为了统计学生成绩，你可以创建一个函数来计算平均分、总分、最高分和最低分。下面是一个简单的例子，假设我们有一个结构体`Student`，其中包含学生的姓名和成绩数组：

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

typedef struct {
    char name[50];
    int scores[10]; // 假设最多有10门课程
} Student;

// 函数原型声明
void calculateStats(Student* student);
double average(int scores[], int num_scores);
int sum(int scores[], int num_scores);
int max_score(int scores[], int num_scores);
int min_score(int scores[], int num_scores);

// 主函数
int main() {
    Student s;
    // 初始化学生信息
    scanf("%s", s.name);
    for (int i = 0; i < 10; i++) {
        scanf("%d", &s.scores[i]);
    }

    // 调用统计函数
    calculateStats(&s);

    return 0;
}

// 统计函数实现
void calculateStats(Student* student) {
    double avg = average(student->scores, 10);
    int total = sum(student->scores, 10);
    int max = max_score(student->scores, 10);
    int min = min_score(student->scores, 10);

    printf("Name: %s\n", student->name);
    printf("Average Score: %.2f\n", avg);
    printf("Total Score: %d\n", total);
    printf("Max Score: %d\n", max);
    printf("Min Score: %d\n", min);
}

// 辅助函数
double average(int scores[], int num_scores) {
    double sum = 0;
    for (int i = 0; i < num_scores; i++) {
        sum += scores[i];
    }
    return sum / num_scores;
}

int sum(int scores[], int num_scores) {
    int result = 0;
    for (int i = 0; i < num_scores; i++) {
        result += scores[i];
    }
    return result;
}

int max_score(int scores[], int num_scores) {
    int max = scores[0];
    for (int i = 1; i < num_scores; i++) {
        if (scores[i] > max) {
            max = scores[i];
        }
    }
    return max;
}

int min_score(int scores[], int num_scores) {
    int min = scores[0];
    for (int i = 1; i < num_scores; i++) {
        if (scores[i] < min) {
            min = scores[i];
        }
    }
    return min;
}
