Answer to Question #332865 in C++ for Cool

Question

1.   Write a program using string functions that determine if the input word is a palindrome. A palindrome word is a word that produces the same word when it is reversed.

Answer 1

#include <string>
#include <algorithm>
#include <cctype>  
#include <iostream>
using namespace std;
int main()
{
    string str,strTest;
    int i=0,j=0;
    cout<<"Enter a word: ";
    getline(cin, str);
    int len= str.length();   // len = length of input string
    
      for(i=0;i<len;i++)
        if(str[i]!=' ')        // overwrite all but spaces
           strTest.push_back(toupper(str[i])); // in upper case
      
 // Test whether the elements in two ranges are equal
    if (equal(strTest.begin(), strTest.begin() + strTest.size() / 2, strTest.rbegin()))
        cout <<  "It is a Palindrome!";
    else
        cout <<  "a";
    cout << endl << endl;

    system("PAUSE");
    return 0;
}
