用的VS，写的字符串的copy 、 cmp 、cat， 在VC环境下运行没有终止，在VS下就终止了

#include "stdafx.h"#include <iostream>using namespace std;char *StrCpy(char *pDest, const char *pSrc){for (int i = 0; '\0' != (pDest[i] = pSrc[i]); i++){}return pDest;}bool StrCmp(const char *pStr, const char *pStr1){bool bFlag = true;for (int i = 0;; i++){if (pStr[i] != pStr1[i]){bFlag = false;break;}}return bFlag;}char *StrCat(char *pDest, const char *pSrc){for (int i = 0; ; i++){if ('\0' == pDest[i]){for (int j = 0; ; j++){pDest[i + j] = pSrc[j];if ('\0' == pSrc[j]){return pDest;}}}}return pDest;}int main(){char cStr1[34] = "NSGDSB!";char cStr2[] = "NSDSB!";char pDest[] = "";char cStr3[] = "dsad";StrCpy(pDest, cStr1);cout << pDest << endl;cout << StrCmp(cStr1, cStr2) << endl;cout << StrCat(cStr1, cStr3) << endl;return 0;}
