用C语言编程，设有若干个人员的数据，其中有学生和教师。学生的数据中包括：姓名、号码、性别、职业、班级。教师的数据包括：姓名、号码、性别、职业、职务。要求输入人员的数据，然后再输出。

以下是用C语言编写的示例代码：

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

#define MAX_NAME_LEN 20
#define MAX_NUM_LEN 10
#define MAX_OCCUPATION_LEN 20
#define MAX_CLASS_LEN 10
#define MAX_POSITION_LEN 20

typedef struct {
    char name[MAX_NAME_LEN];
    char num[MAX_NUM_LEN];
    char gender;
    char occupation[MAX_OCCUPATION_LEN];
    char class[MAX_CLASS_LEN];
} Student;

typedef struct {
    char name[MAX_NAME_LEN];
    char num[MAX_NUM_LEN];
    char gender;
    char occupation[MAX_OCCUPATION_LEN];
    char position[MAX_POSITION_LEN];
} Teacher;

void input_student(Student* student);
void input_teacher(Teacher* teacher);
void output_student(const Student* student);
void output_teacher(const Teacher* teacher);

int main() {
    int n;
    printf("Enter the number of people: ");
    scanf("%d", &n);

    Student* students = (Student*) malloc(n * sizeof(Student));
    Teacher* teachers = (Teacher*) malloc(n * sizeof(Teacher));

    printf("Enter the data of %d students:\n", n);
    for (int i = 0; i < n; i++) {
        input_student(&students[i]);
    }

    printf("Enter the data of %d teachers:\n", n);
    for (int i = 0; i < n; i++) {
        input_teacher(&teachers[i]);
    }

    printf("The data of %d students:\n", n);
    for (int i = 0; i < n; i++) {
        output_student(&students[i]);
    }

    printf("The data of %d teachers:\n", n);
    for (int i = 0; i < n; i++) {
        output_teacher(&teachers[i]);
    }

    free(students);
    free(teachers);

    return 0;
}

void input_student(Student* student) {
    printf("Enter the name of the student: ");
    scanf("%s", student->name);
    printf("Enter the number of the student: ");
    scanf("%s", student->num);
    printf("Enter the gender of the student (M or F): ");
    scanf(" %c", &student->gender);
    printf("Enter the occupation of the student: ");
    scanf("%s", student->occupation);
    printf("Enter the class of the student: ");
    scanf("%s", student->class);
}

void input_teacher(Teacher* teacher) {
    printf("Enter the name of the teacher: ");
    scanf("%s", teacher->name);
    printf("Enter the number of the teacher: ");
    scanf("%s", teacher->num);
    printf("Enter the gender of the teacher (M or F): ");
    scanf(" %c", &teacher->gender);
    printf("Enter the occupation of the teacher: ");
    scanf("%s", teacher->occupation);
    printf("Enter the position of the teacher: ");
    scanf("%s", teacher->position);
}

void output_student(const Student* student) {
    printf("Name: %s\n", student->name);
    printf("Number: %s\n", student->num);
    printf("Gender: %c\n", student->gender);
    printf("Occupation: %s\n", student->occupation);
    printf("Class: %s\n", student->class);
}

void output_teacher(const Teacher* teacher) {
    printf("Name: %s\n", teacher->name);
    printf("Number: %s\n", teacher->num);
    printf("Gender: %c\n", teacher->gender);
    printf("Occupation: %s\n", teacher->occupation);
    printf("Position: %s\n", teacher->position);
}
