    ob2.get();

    ob1==ob2;

    ob1+ob2;

    

   

           

    return 0;    

}    

OUTPUT 1

Enter the first string: hello

 Enter the second string: world

Strings are not equal

Concatenated String: hello world

OUTPUT 2

 Enter the first string: hello

 Enter the second string: hello

Given Strings are equal

Concatenated String: hello hello
