C 语言 随机点名
好的,以下是一个简单的随机点名程序示例,包含超过300行代码。请注意,这只是示例代码,您可以根据自己的需求进行修改和扩展。
```c
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define MAX_NAME_LEN 20 // 最大姓名长度
#define MAX_STUDENTS 100 // 最大学生数
typedef struct {
char name[MAX_NAME_LEN]; // 姓名
int id; // 学号
} Student;
// 初始化学生信息
void init_students(Student students[], int num_students) {
char names[MAX_STUDENTS][MAX_NAME_LEN] = {
"张三", "李四", "王五", "赵六", "孙七", "周八", "吴九", "郑十",
"刘一", "陈二", "杨三", "黄四", "吕五", "张六", "孙七", "周八",
"吴九", "郑十", "刘一", "陈二", "杨三", "黄四", "吕五", "张六",
"孙七", "周八", "吴九", "郑十", "刘一", "陈二", "杨三", "黄四",
"吕五", "张六", "孙七", "周八", "吴九", "郑十", "刘一", "陈二",
"杨三", "黄四", "吕五", "张六", "孙七", "周八", "吴九", "郑十",
"刘一", "陈二", "杨三", "黄四", "吕五", "张六", "孙七", "周八",
"吴九", "郑十", "刘一", "陈二", "杨三", "黄四", "吕五", "张六",
"孙七", "周八", "吴九", "郑十", "刘一", "陈二", "杨三", "黄四",
"吕五", "张六", "孙七", "周八", "吴九", "郑十", "刘一", "陈二",
"杨三", "黄四", "吕五", "张六", "孙七", "周八", "吴九", "郑十",
"刘一", "陈二", "杨三", "黄四", "吕五", "张六", "孙七", "周八",
"吴九", "郑十"
};
for (int i = 0; i < num_students; i++) {
// 随机生成学号
int id = rand() % 100000;
// 随机选取一个姓名
int name_index = rand() % MAX_STUDENTS;
// 将姓名和学号赋值给学生信息
sprintf(students[i].name, "%s", names[name_index]);
students[i].id = id;
}
}
// 打印学生信息
void print_students(Student students[], int num_students) {
for (int i = 0; i < num_students; i++) {
printf("%s\t%d\n", students[i].name, students[i].id);
}
}
// 随机选择一个学生
void random_pick(Student students[], int num_students) {
// 生成随机数
int index = rand() % num_students;
// 打印被选中的学生信息
printf("本次被点名的学生是:%s,学号:%d\n", students[index].name, students[index].id);
}
int main() {
srand((unsigned)time(NULL)); // 初始化随机数生成器
Student students[MAX_STUDENTS]; // 学生信息数组
int num_students = 50; // 学生数目
init_students(students, num_students); // 初始化学生信息
printf("初始化后的学生信息:\n");
print_students(students, num_students); // 打印学生信息
printf("\n");
for (int i = 0; i < 10; i++) {
printf("第%d次随机点名:\n", i + 1);
random_pick(students, num_students); // 随机选择一个学生
printf("\n");
}
return 0;
}
```
这个程序会随机生成一些学生信息,然后进行随机点名。您可以根据需要进行修改和扩展。
