教师信息管理系统C语言编程

教师信息管理系统是一个用于管理教师信息的系统，它需要实现以下功能：

1. 添加教师信息：能够输入教师的基本信息，如姓名、性别、年龄、职称、学历等。

2. 修改教师信息：能够对已有的教师信息进行修改。

3. 删除教师信息：能够删除系统中的某个教师信息。

4. 查询教师信息：能够根据条件查询系统中的教师信息。

5. 显示所有教师信息：能够显示系统中所有的教师信息。

下面是一个简单的C语言编程示例，实现了教师信息管理系统的基本功能：

```c

#include

#include

typedef struct {

char name[20];

char gender;

int age;

char title[20];

char education[50];

} Teacher;

void add_teacher(Teacher *teachers, char *name, char gender, int age, char title[], char education[]);

void modify_teacher(Teacher *teachers, int index, char *old_name, char *new_name, char *old_gender, char *new_gender, int old_age, char *new_title, char *new_education);

void delete_teacher(Teacher *teachers, int index);

void query_teacher(Teacher *teachers, char *keyword);

void display_teachers(Teacher *teachers);

int main() {

Teacher teachers[100];

add_teacher(teachers, "张三", 'M', 25, "教授", "清华大学");

add_teacher(teachers, "李四", 'F', 30, "副教授", "北京大学");

display_teachers(teachers);

return 0;

}

void add_teacher(Teacher *teachers, char *name, char gender, int age, char title[], char education[]) {

strcpy(teachers[0].name, name);

teachers[0].gender = gender;

teachers[0].age = age;

strcpy(teachers[0].title, title);

strcpy(teachers[0].education, education);

}

void modify_teacher(Teacher *teachers, int index, char *old_name, char *new_name, char *old_gender, char *new_gender, int old_age, char *new_title, char *new_education) {

if (index < 0 || index >= sizeof(teachers)) {

printf("索引超出范围！

");

return;

}

strcpy(teachers[index].name, new_name);

teachers[index].gender = new_gender;

teachers[index].age = old_age;

strcpy(teachers[index].title, new_title);

strcpy(teachers[index].education, new_education);

}

void delete_teacher(Teacher *teachers, int index) {

if (index < 0 || index >= sizeof(teachers)) {

printf("索引超出范围！

");

return;

}

for (int i = index; i < sizeof(teachers)
• 1; i++) {

teachers[i] = teachers[i + 1];

}

sizeof(teachers)--;

}

void query_teacher(Teacher *teachers, char *keyword) {

for (int i = 0; i < sizeof(teachers)
• 1; i++) {

if (strcmp(teachers[i].name, keyword) == 0) {

printf("找到教师：%s，性别：%c，年龄：%d，职称：%s，学历：%s

", teachers[i].name, teachers[i].gender, teachers[i].age, teachers[i].title, teachers[i].education);

return;

}

}

printf("未找到教师：%s，性别：%c，年龄：%d，职称：%s，学历：%s

", keyword, teachers[i].gender, teachers[i].age, teachers[i].title, teachers[i].education);

}

void display_teachers(Teacher *teachers) {

for (int i = 0; i < sizeof(teachers)
• 1; i++) {

printf("教师编号：%d，姓名：%s，性别：%c，年龄：%d，职称：%s，学历：%s

", i + 1, teachers[i].name, teachers[i].gender, teachers[i].age, teachers[i].title, teachers[i].education);

}

}

```

这个示例中，我们定义了一个`Teacher`结构体来存储教师的信息，然后实现了`add_teacher`、`modify_teacher`、`delete_teacher`、`query_teacher`和`display_teachers`函数来实现教师信息管理系统的基本功能。在`main`函数中，我们创建了一个`Teacher`数组来存储教师信息，并调用这些函数来演示如何添加、修改、删除和查询教师信息。
