typedef struct TeachInfo {

int main() {

}

1. 结构体

struct teachInfo
{
    char *name;        // 教师姓名
    char *sex;            // 性别
    int age;            // 年龄
    float salary;        // 薪水
}

2. 定义结构体数组

struct teachInfo teach_info[5];

for(int i = 1; i < 5; i++)
{
   scanf("%s", teach_info[i].name);
   scanf("%s", teach_info[i].sex);
   scanf("%d", &teach_info[i].age);
   scanf("%f", &teach_info[i].salary);
}

3. 赋值

strcpy(teach_info[0].name, "张三");
strcpy(teach_info[0].sex, "男");
teach_info[0].age = 40;
teach_info[0].salary = 5203.4;

teach_info[2], teach_info[3]以此类推。

4. 输出

printf("教师姓名\t性别\t年龄\t薪水\n");
for(int i = 0; i < 5; i++)
{
   printf("%s\t%s\t%d\t%f\n", teach_info[i].name, teach_info[i].sex, teach_info[i].age, teach_info[i].salary);
}
