C++ Program to Check Whether C-Style String is Palindrome or not

#include <iostream>

#include <string.h>

using namespace std;

int main()

{

    char str1[50], str2[50];

    int i, j;

    cout<<"Enter a String: ";

    cin.getline(str1, 50);

    for(i=strlen(str1)-1, j=0; str1[j]!='\0'; i--, j++)

    {

        str2[j] = str1[i];

    }

    str2[j]= '\0';

    if(strcmp(str1, str2))

        cout<<"String is not Palindrome";

    else

        cout<<"String is Palindrome";

    return 0;

}

OUTPUT:

Enter a String: madam

String is Palindrome

C++ Program to Check String Object is Palindrome or not

#include <iostream>

#include <string.h>

using namespace std;

int main()

{

    string str1, str2;

    int i, j;

    cout<<"Enter a String: ";

    getline(cin, str1);

    str2 = str1;

    j = str1.length();

    j--;

    for(i=0; i<str1.length(); i++, j--)

    {

        str2[j] =str1[i];

    }

    if(str1 == str2)

        cout<<"\nString is Palindrome";

    else

        cout<<"\nString is not Palindrome";

    return 0;

}

OUTPUT:

Enter a String: mam

String is Palindrome
