针对学生成绩管理系统，利用二维数组实现多门课程管理功能模块的设计

Answer 1

解析：首先需要定义一个二维数组score，用于存放学生的成绩。然后实现输入成绩的函数inputScore，输出成绩的函数outputScore，获取学生总成绩的函数getStuScore，获取课程总成绩的函数getCouScore，输出学生平均成绩的函数outputStuAve和输出课程平均成绩的函数outputCouAve。

代码如下：

#include <stdio.h>

#define M 30
#define N 5

void inputScore(int score[M][N], int len);
void outputScore(int score[M][N], int len);
void getStuScore(int score[M][N], int len);
void getCouScore(int score[M][N], int len);
void outputStuAve(int score[M][N], int len);
void outputCouAve(int score[M][N], int len);

int main() {
    int score[M][N];
    inputScore(score, M * N);
    outputScore(score, M * N);
    getStuScore(score, M * N);
    getCouScore(score, M * N);
    outputStuAve(score, M * N);
    outputCouAve(score, M * N);
    return 0;
}

void inputScore(int score[M][N], int len) {
    for (int i = 0; i < M; i++) {
        for (int j = 0; j < N; j++) {
            scanf("%d", &score[i][j]);
        }
    }
}

void outputScore(int score[M][N], int len) {
    for (int i = 0; i < M; i++) {
        for (int j = 0; j < N; j++) {
            printf("%d ", score[i][j]);
        }
        printf("
");
    }
}

void getStuScore(int score[M][N], int len) {
    for (int i = 0; i < M; i++) {
        int sum = 0;
        for (int j = 0; j < N; j++) {
            sum += score[i][j];
        }
        score[i][N] = sum;
    }
}

void getCouScore(int score[M][N], int len) {
    for (int j = 0; j < N; j++) {
        int sum = 0;
        for (int i = 0; i < M; i++) {
            sum += score[i][j];
        }
        score[M][j] = sum;
    }
}

void outputStuAve(int score[M][N], int len) {
    for (int i = 0; i < M; i++) {
        printf("%d ", score[i][N] / N);
    }
    printf("
");
}

void outputCouAve(int score[M][N], int len) {
    for (int j = 0; j < N; j++) {
        printf("%d ", score[M][j] / M);
    }
    printf("
");
}
