Hey I'm working on a code where I have to use the grow method to double the size of an existing rectangle.

my first rectangle is

Rectangle recOne = new Rectangle(10, 15, 5, 8);

as you can see my width is 5 and height is 8.

I further proceeded to do this :

recOne.grow(5, 4);

since the grow method is (width + 2h, heigth + 2v)

The result I'm receiving for the new rectanlge is (9, 16) and not (10, 16). A friend of mine who is more advanced in coding told me this had to do with integer division.

sorry that's recOne.grow(5/2, 4)

5 / 2 in integer division equals 2.  Any fraction is truncated (cut off).  The plus side to this is that 5 % 2 = 1, the modulus ( remainder ) is one.

If you are using C++ you might just add decimal points to your elements and deal with float datatypes..
