Byte alignment is one of the most frequently learned points in an interview written exam.There are only a few steps you can take to calculate the size of a struct.1. Confirm the length of all members in the structThis table can be referenced.

We can define class members static using static keyword. When we declare a member of a class as static it means no matter how many objects of the class be created, there is only One copy of the static member. A Static member is shared by all
