hi,
I am writng a program that takes a string and it must output if it is a palindrome,
A palindrome is a string that is spelled and read the same way forward and backward, it workes fine with one word but if there is spaces or capital lettersor commas it won't work I used getline but without any effect.here is the code.


CODE
Code: ( text )
#include <iostream>
#include <string>
using namespace std;
int main ()

{
    char s[100];
    int i,j;
    bool match=true;
    cin.getline(s,100,'\n');
    cout<<endl;
    i=0;
    j=strlen(s)-1;//because of the \0
    
    
    
    while(match&&(i<j))
    {
        if(s[i]!=s[j])
            match=false;
        i++;
        j--;
    }
    if (match)
        cout<<"It is a palindrome"<<endl;
    else
        cout<<"It is not a palindrome"<<endl;
    
    return 0;
}

You might want to check out this earlier discussion that may help you with this problem. The idea is to use recursion to compare the first character with the last character, subtract 1 and call it again. It should work with spaces, punctuation and even case sensitive.

Hope it pushes you in the right direction. smile.gif
