C++实现判断字符串是否回文实例解析

#include <iostream>using namespace std;#define Max_String_Len 100#include "SqStack.h"//判断字符串是否回文bool ispalindrome(char *in_string){ SqStack <char> s(Max_String_Len);    char deblankstring[Max_String_Len], c; int i = 0; //过滤空格字符 while(*in_string != '/0'){    if(*in_string != ' ') deblankstring[i++] = *in_string; in_string++;  }  deblankstring[i] = '/0'; //有效字符依次入栈 i = 0; while(deblankstring[i] != '/0')    s.Push(deblankstring[i++]); //从栈中弹出字符依次比较    i = 0;  while(!s.Empty()){ c = s.Top();    s.Pop();    if(c != deblankstring[i])      return false;      i++;  } return true;}int main(){  char instring[Max_String_Len];  cout << "input a string:" << endl;  cin.get(instring, Max_String_Len);  //cout<<instring;  if(ispalindrome(instring))    cout << "/"" << instring << "/"" << " is a palindrome." << endl;  else    cout << "/"" << instring << "/"" << " is not a palindrome." << endl;  system("pause");  return 0;}
