用c语言编写一个简单程序

某托儿所收2岁到6岁的孩子,2岁,3岁孩子进小班(Lower class);4岁孩子进中班(Middle class);5岁,6岁孩子进大班(Higher class).编写程序,在主函数中输入孩子年龄,通过调用一个函数(该函数使用switch语句),输出年龄及进入的班号,如:输入:3输出:age:3,enter Lower class 如果输入了其他年龄,输出提示信息"您输入有误!"

#include <stdio.h>

int main(){
    int age;
    scanf("%d",&age);
    switch (age)
    {
    case 2:
    case 3:
        printf("age: %d,enter Lower class\n",age);
        break;
    case 4:
        printf("age: %d,enter Middle class\n",age);
        break;
    case 5:
    case 6:
        printf("age: %d,enter Higher class\n",age);
        break;
    default:
        printf("您输入有误!\n");
    }
    return 0;
}

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

void main()
{
    int age = 0;
    scanf("%d", &age);
    switch (age)
    {
    case 2:
        printf("age:%d,enter Lower class", age);
        break;
    case 3:
        printf("age:%d,enter Lower class",age);
        break;
    case 4:
        printf("age:%d,enter Middle class", age);
        break;
    case 5:
        printf("age:%d,enter Higher class", age);
        break;
    case 6:
        printf("age:%d,enter Higher class", age);
        break;
    default:
        printf("您输入有误!");
        break;
    }
}
