使用得到安全 [英] Use gets Safely
问题描述
我写了这个程序，保证安全使用。
#include< stdio.h>
int main（void）
{
char name [588 + 1];
printf（"输入你的姓氏："）;
fflush（stdout）;
printf（" Hi％s \ n"，gets（name））;
返回0;
}
你看，世界上最长的姓氏是588个字符，这里解释为

I wrote this program which guarantees to use gets safely.
#include <stdio.h>
int main(void)
{
char name[588+1];
printf("Enter your last name: ");
fflush(stdout);
printf("Hi %s\n",gets(name));
return 0;
}
You see, the longest last name in the world is 588 characters, as
explained here:

So, my program works for everyone in the world. Guaranteed.

如果他们输入额外的十个字母，只是为了好玩怎么办？
如果他们喂它100 MB怎么办？二进制文件？
What if they type in an extra ten letters, just for fun?
What if they feed it a 100 MB binary file?

或者如果他们有自己名字的拼写错误（在588
字符中不太可能）。

究竟如何确保用户被限制输入
a真正的姓氏，以及它如何确保约束
最长的姓氏/仍然保持/何时运行？
很好的尝试。

Exactly how does it ensure that the user is constrained to enter
a genuine last name, and how does it ensure that the constraints
for a longest last name /still hold/ when it runs?
Nice try.
