c语言 计算学生平均成绩，计算各科成绩最高分

以下是计算学生平均成绩和各科成绩最高分的C语言代码示例：

#include <stdio.h>

struct Student {
    int id;
    char name[50];
    char className[50];
    float mathScore;
    float englishScore;
    float computerScore;
};

int main() {
    struct Student students[100];
    int numStudents;

    // 从用户输入获取学生信息
    printf("请输入学生人数：");
    scanf("%d", &numStudents);

    for (int i = 0; i < numStudents; i++) {
        printf("请输入第%d个学生的学号：", i + 1);
        scanf("%d", &students[i].id);

        printf("请输入第%d个学生的姓名：", i + 1);
        scanf("%s", students[i].name);

        printf("请输入第%d个学生的班级：", i + 1);
        scanf("%s", students[i].className);

        printf("请输入第%d个学生的数学成绩：", i + 1);
        scanf("%f", &students[i].mathScore);

        printf("请输入第%d个学生的英语成绩：", i + 1);
        scanf("%f", &students[i].englishScore);

        printf("请输入第%d个学生的计算机成绩：", i + 1);
        scanf("%f", &students[i].computerScore);
    }

    // 计算每个学生的平均成绩
    for (int i = 0; i < numStudents; i++) {
        float averageScore = (students[i].mathScore + students[i].englishScore + students[i].computerScore) / 3;
        printf("学生%d的平均成绩为：%.2f\n", students[i].id, averageScore);
    }

    // 计算各科成绩的最高分
    float maxMathScore = students[0].mathScore;
    float maxEnglishScore = students[0].englishScore;
    float maxComputerScore = students[0].computerScore;

    for (int i = 1; i < numStudents; i++) {
        if (students[i].mathScore > maxMathScore) {
            maxMathScore = students[i].mathScore;
        }
        if (students[i].englishScore > maxEnglishScore) {
            maxEnglishScore = students[i].englishScore;
        }
        if (students[i].computerScore > maxComputerScore) {
            maxComputerScore = students[i].computerScore;
        }
    }

    printf("数学成绩的最高分为：%.2f\n", maxMathScore);
    printf("英语成绩的最高分为：%.2f\n", maxEnglishScore);
    printf("计算机成绩的最高分为：%.2f\n", maxComputerScore);

    return 0;
}
