昨天看的道题目，试了下，两个程序，第一个貌似正常，结果输出数组越界，第二个尝试稍微改动，结果程序崩溃....求助....已知 strcpy函数的原型是 char *strcpy (char *strDest,const char *strSrc);其中strDest是目的字符串 strSrc是源字符串，不能调用C++/C的字符串库函数写出strcpy函数？？？char *strcpy (char *strDest,const char *strSrc)上面是题目#include<iostream>using namespace std;char *strcpy (char *strDe...
