Lebanese flag using switch

Maya (15)
I am writing a program that draws the Lebanese flag in 2 sizes chosen by the user, but at execution, I am always getting the default case. Any idea why is this happening?
Thank you!

size is an integer value but in switch-case you check it as a character.
'1' --> This is character
1 --> This is integer value

Also...don't use void main()...use int main() instead.
