Fix it to produce the following output
----------------------------------
Comparison:     [1]
My_int:         [0]
My_char:        [0]
My_string:      [Hola]
----------------------------------


----------------------------------
Comparison:     [1]
My_int:         [123]
My_char:        [z]
My_string:      [Au revoir]
----------------------------------


----------------------------------
Comparison:     [0]
My_int:         [4]
My_char:        [d]
My_string:      [Ciao]
----------------------------------


You can only modify the second and third assignation blocks in the code (see the comments)
You can only change the present assignation blocks code and you cannot add any lines of code
