    amount = sizeof(people) / sizeof(INFO);  //加上这行，输入完，未打印结构体信息

    printf("Name                    Age\n");
    printf("---------------------------\n\n");

    for(i=0; i < amount; i++)

    }
}

int main(void)
{
    INFO people[N];

    input(people);

    return 0;
}

这个程序会要求职时输入3组人的信息，多于3组有提示，我的问题就是，比如我要输入4组，这个amount，我这个代码貌似有错amount = sizeof(people) / sizeof(INFO);  //加上这行，输入完，未打印结构体信息如何定？或者有没有其他办法修改我这个代码

请高手指点，谢谢
