Problem 6: (4 pts): Write a function that takes as an input parameter a string. It should return a Boolean value indicating whether the string is a palindrome or not. INPUT: “mom"->true “palindrome”->false “amanaplanpanama"->true

Answer 1

#include <iostream>
#include <string.h>
using namespace std;

string function6(string str);

int main()
{
    function6("palindrome");
    function6("amanaplanpanama");
    function6("mom");
    return 0;
}

string function6(string str){
    int i = 0, j = str.length()-1;
    // i is the first index
    // j is the last index
    // compare char value at i and j and if not same return false
    // else at the end return and print true
    while(i<j){
        if(str[i]!=str[j]){
            cout<<"false"<<endl;
            return "false";
        }
        i++;
        j--;
    }
    cout<<"true"<<endl;
    return "true";
}
