判断是否为回文

//判断是否为回文——判断用户输入的字符串是否为回文。回文是指正反拼写形式都是一样的词，譬如“racecar”。#define _CRT_SECURE_NO_WARNINGS#include <iostream>using namespace std;bool IsPlalindromeW(const wchar_t* str){size_t len = wcslen(str);for (int i = 0; i < len; ++i){if (str[i] != str[len - i - 1])return false;}return true;}bool IsPlalindrome(const char* str){if (str == NULL)return false;setlocale(LC_ALL, "chs");int len = mbstowcs(NULL, str, NULL);if (len <= 0)return false;wchar_t* dst = new wchar_t[len + 1];int change = mbstowcs(dst, str, len + 1);bool bRes = IsPlalindromeW(dst);delete[] dst;setlocale(LC_ALL, "");return bRes;}int main(int argc, char* argv[]){char* str = "斗鸡山上山鸡斗";cout << boolalpha;cout << IsPlalindrome(str) << endl;system("pause");return 0;}
