Answer:
<u>How to implement a stack in C using an array?</u>
A stack is a linear data structure that follows the Last in, First out principle (i.e. the last added elements are removed first).
This abstract data type can be implemented in C in multiple ways. One such way is by using an array.
Pro of using an array:
No extra memory required to store the pointers.
Con of using an array:
The size of the stack is pre-set so it cannot increase or decrease.
Answer:
False
Explanation:
An instance of an abstract class cannot be created through the constructor of the class, because it does not have a complete implementation. Though, it is possible to have references of an abstract type class. Abstract classes are incomplete structures and you would have to build onto it before you are able to use it.
