实验环境中，给出含有n个学生的成绩表，每条记录由学号，姓名和分数组成，编写具体函数完成下列操作设计一个菜单操作界面，实习录入学生基本信息，直接插入排序，折半插入排序，冒泡排序，快速排序，简单选择排序，输入学生信息，退出等基本操作的C语言完整代码

好的，以下是一个实现上述功能的C语言代码，其中包含一个菜单界面，可以让用户选择需要进行的操作： ```c #include <stdio.h> #include <string.h> #define MAX_STUDENT_NUM 100 struct Student { int id; char name[20]; int score; }; // 录入学生信息 void inputStudentInfo(struct Student *students, int n) { for (int i = 0; i < n; i++) { printf("请输入第%d个学生的信息：\n", i + 1); printf("学号："); scanf("%d", &(students[i].id)); printf("姓名："); scanf("%s", students[i].name); printf("分数："); scanf("%d", &(students[i].score)); } } // 直接插入排序 void straightInsertSort(struct Student *students, int n) { for (int i = 1; i < n; i++) { struct Student temp = students[i]; int j = i - 1; while (j >= 0 && students[j].id > temp.id) { students[j + 1] = students[j]; j--; } students[j + 1] = temp; } } // 折半插入排序 void binaryInsertSort(struct Student *students, int n) { for (int i = 1; i < n; i++) { struct Student temp = students[i]; int left = 0, right = i - 1; while (left <= right) { int mid = (left + right) / 2; if (students[mid].id > temp.id) { right = mid - 1; } else { left = mid + 1; } } for (int j = i - 1; j >= left; j--) { students[j + 1] = students[j]; } students[left] = temp; } } // 冒泡排序 void bubbleSort(struct Student *students, int n) { for (int i = 0; i < n - 1; i++) { for (int j = 0; j < n - i - 1; j++) { if (students[j].id > students[j + 1].id) { struct Student temp = students[j]; students[j] = students[j + 1]; students[j + 1] = temp; } } } } // 快速排序 void quickSort(struct Student *students, int left, int right) { if (left >= right) { return; } struct Student pivot = students[left]; int i = left, j = right; while (i < j) { while (i < j && students[j].id >= pivot.id) { j--; } students[i] = students[j]; while (i < j && students[i].id <= pivot.id) { i++; } students[j] = students[i]; } students[i] = pivot; quickSort(students, left, i - 1); quickSort(students, i + 1, right); } // 简单选择排序 void simpleSelectionSort(struct Student *students, int n) { for (int i = 0; i < n - 1; i++) { int minIndex = i; for (int j = i + 1; j < n; j++) { if (students[j].id < students[minIndex].id) { minIndex = j; } } if (minIndex != i) { struct Student temp = students[i]; students[i] = students[minIndex]; students[minIndex] = temp; } } } // 输出学生信息 void printStudents(struct Student *students, int n) { printf("学号\t姓名\t分数\n"); for (int i = 0; i < n; i++) { printf("%d\t%s\t%d\n", students[i].id, students[i].name, students[i].score); } } int main() { struct Student students[MAX_STUDENT_NUM]; int n = 0; int choice = 0; while (1) { printf("-----------------菜单-----------------\n"); printf("1. 录入学生信息\n"); printf("2. 直接插入排序\n"); printf("3. 折半插入排序\n"); printf("4. 冒泡排序\n"); printf("5. 快速排序\n"); printf("6. 简单选择排序\n"); printf("7. 输出学生信息\n"); printf("8. 退出\n"); printf("---------------------------------------\n"); printf("请输入菜单选项："); scanf("%d", &choice); switch (choice) { case 1: printf("请输入学生人数："); scanf("%d", &n); inputStudentInfo(students, n); printf("学生信息录入成功！\n"); break; case 2: straightInsertSort(students, n); printf("直接插入排序完成！\n"); break; case 3: binaryInsertSort(students, n); printf("折半插入排序完成！\n"); break; case 4: bubbleSort(students, n); printf("冒泡排序完成！\n"); break; case 5: quickSort(students, 0, n - 1); printf("快速排序完成！\n"); break; case 6: simpleSelectionSort(students, n); printf("简单选择排序完成！\n"); break; case 7: printStudents(students, n); break; case 8: printf("程序已退出！\n"); return 0; default: printf("无效的菜单选项！\n"); break; } } return 0; } ``` 注意，上述代码中的每个排序方法都实现了从小到大的排序功能，如果需要从大到小排序，可以通过修改比较函数来实现。同时，为了简化问题，上述代码中没有进行输入检查和错误处理，实际应用中需要根据具体情况进行处理。
