判断是否为回文类型的字符串

#include<iostream>
using namespace std;

bool Check_huiweng(const char* pstr, int n)
{
    if (pstr == NULL)
        return false;
    char* front = const_cast<char*>(pstr);
    char* back = const_cast<char*>(pstr)+ n - 1;

    while (front < back)
    {
        if (*front != *back)
        {
            return false;
        }
        front++;
        back--;
    }
    return true;
}

void main()
{
    char* str=(char*)malloc(sizeof(char));
    cout << "plz enter a string:" << endl;
    cin >> str;
    int N = strlen(str);
    bool result = Check_huiweng(str,N);
    
    system("pause");
