hi there. I have noticed that in the lesson you didn't gave the int datatype a size parameter. Does it mean that int parameter can hold lby default any integer no matter how many characters it consists of?

Answer 1

u can choose the size for eg. whe is to put age u can put int(3),cause nowadays we dont find persons with ages more than 999,for cell phone number u can use int (15) or more but according to the country
