Implementation of Queue using circular array

#1

In the Constructor why we take default size 7.
If we Create an Object of Queue as q(10) then default size will be changed or not?

#2

Hey, default value is given to a variable when it is mostly equal to a given value but it is sometime different.
So,here we take default size 7 just to keep a default value .
Yes,q(10) will change the size of queue but not default value.
So,for current queue size is 10 but for next time if you don’t give a value then size will be 7.If you give a size then size will be equal to that value.
