strcpy是C语言标准库中的一个函数,其原型定义在 <string.h> 头文件中。该函数用于将一个字符串复制到另一个字符串中,虽然 strcpy 在字符串操作中非常常用,但它也带来了显著的安全隐患,主要是因为它不检查目标缓冲区的大小,这可能导致缓冲区溢出 如果源字符串的长度超过了目标缓冲区的大小,strcpy 会继续复制字符...
It reads up to n-1 characters into a buffer and terminates the string with a null character. 它将最多 n-1 个字符读入缓冲区并以空字符终止字符串。 If fewer than n-1 characters are in the current line, it reads up to and including the newline and terminates the string with a null cha...
