How to compare two strings c++ without using strcmp

Question

Problem:

Well, comparing two strings lengths in a c++ program is quite easy. I wonder if I can compare two strings c++ without using strcmp! Do you have any idea guys? Please, share with me.
Thanks for your concern.

As far as your problem is concern, yes! there are some other ways to compare two strings in c++. We can use Relational operators and std:: Compare() function. Hence I love the second option, I am going with it. 

#include <iostream>
using namespace std; 
void compareString(string str1, string str2){ 
    int n = str1.compare(str2); 
    if (n != 0) 
        cout << str1 << " is not as like as "
             << str2 << endl; 
    if (n > 0) 
        cout << str1 << " is larger than "
             << str2 << endl; 
    else
        cout << str2 << " is larger than "
             << str1 << endl; 
}
int main(){ 
    string str1("Hello-World"); 
    string str2("World-Hi"); 
    compareString(str1, str2); 
    return 0; 
}

Here I declared two different string into two differents variable str1 and str2. And then pass these string through a function compareString() as parameters. The program should throw an output

Hello-World is not as like as World-Hi
World-Hi is larger than Hello-World

Leave me a kudos if the problem is solved. Thanks!
