C语言用结构体数组实现以下功能：有5个学生，每个学生的数据包括学号、姓名、数学课成绩、英语课成绩和计算机课成绩。从键盘输入5个学生数据，要求输出每门课的平均成绩，以及三门课总分最高的学生数据（包括学号、姓名、每门课的成绩、总分、平均分）

以下是用C语言结构体数组实现该功能的代码示例：

#include <stdio.h>

struct Student {
    int number;
    char name[20];
    int mathScore;
    int englishScore;
    int computerScore;
    int totalScore;
    float averageScore;
};

int main() {
    struct Student students[5];
    int maxTotalScore = 0;
    int maxTotalScoreIndex = 0;

    // 输入学生数据
    for (int i = 0; i < 5; i++) {
        printf("请输入第%d个学生的学号：", i + 1);
        scanf("%d", &students[i].number);
        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个学生的数学成绩：", i + 1);
        scanf("%d", &students[i].mathScore);
        printf("请输入第%d个学生的英语成绩：", i + 1);
        scanf("%d", &students[i].englishScore);
        printf("请输入第%d个学生的计算机成绩：", i + 1);
        scanf("%d", &students[i].computerScore);

        // 计算总分和平均分
        students[i].totalScore = students[i].mathScore + students[i].englishScore + students[i].computerScore;
        students[i].averageScore = students[i].totalScore / 3.0;

        // 更新最高总分学生的索引
        if (students[i].totalScore > maxTotalScore) {
            maxTotalScore = students[i].totalScore;
            maxTotalScoreIndex = i;
        }
    }

    // 输出每门课的平均成绩
    printf("每门课的平均成绩：\n");
    float mathAverage = 0, englishAverage = 0, computerAverage = 0;
    for (int i = 0; i < 5; i++) {
        mathAverage += students[i].mathScore;
        englishAverage += students[i].englishScore;
        computerAverage += students[i].computerScore;
    }
    mathAverage /= 5;
    englishAverage /= 5;
    computerAverage /= 5;
    printf("数学课平均成绩：%f\n", mathAverage);
    printf("英语课平均成绩：%f\n", englishAverage);
    printf("计算机课平均成绩：%f\n", computerAverage);

    // 输出三门课总分最高的学生数据
    printf("三门课总分最高的学生数据：\n");
    printf("学号：%d\n", students[maxTotalScoreIndex].number);
    printf("姓名：%s\n", students[maxTotalScoreIndex].name);
    printf("数学成绩：%d\n", students[maxTotalScoreIndex].mathScore);
    printf("英语成绩：%d\n", students[maxTotalScoreIndex].englishScore);
    printf("计算机成绩：%d\n", students[maxTotalScoreIndex].computerScore);
    printf("总分：%d\n", students[maxTotalScoreIndex].totalScore);
    printf("平均分：%f\n", students[maxTotalScoreIndex].averageScore);

    return 0;
}
