Write a program in C++ to check whether a number is Lychrel number or not

#include

{
    return (num == numReverse(num));
}

{
    long long int temp = num;
    long long int rev;
    for (int i = 0; i < iterCount; i++)
    {
        rev = numReverse(temp);
        if (is_Palindrome(rev + temp))
            return false;
        temp = temp + rev;
    }
    return true;
}
int main()

    if (l==0)

    }
    else
