Answer 2

can you explain where is the fault

Answer 3

You have used wrong format specifier which results in wrong output.
Change %d to %f and it will be Ok.

Answer 4

ABADA S first, logically 23.678901*4 =! 1958230209 in theout put.
And 23.678901 is not an integer so we need to put %f to display the result of 4*23.678901 instead of %d

Answer 5

AnonymousGuy yes I know , that's technically true but my goal is to have right unswer for the multiplication why I would print a false result ? . I'm sure this will confuse lot of people especially beginners like me, that's why we must change it to %f in the course

Answer 6

Hadjer😁

Yes, you are right..23.678901 is not an integer but it is not like that you cannot print it using %d..you can use any format specifier..(obviously output will depend upon format specifier)
