Answer / rohit sah
An Abstract Base Class is a class that is not intended to be instantiated itself. Rather, it is intended strictly for use as a base for other classes. To prevent instantiation, an ABC will typically contain at least one pure virtual function.
The point of an ABC is to separate the interface of a group of classes from the implementation of the functions that make up the interface. This allows other code to ignore differences in how these functions are carried out. An ABC creates a contract between its descendants and any other code that uses them. The descendants must implement a certain set of functions. Code that uses them must use those functions to access whatever it is the object involved represents.

Why do we need function?
Assume an array of structure is in order by studentID field of the record, where student IDs go from 101 to 500. Write the most efficient pseudocode algorithm you can to find the record with a specific studentID if every single student ID from 101 to 500 is used and the array has 400 elements. Write the most efficient pseudocode algorithm you can to find a record with a studentID near the end of the IDs, say in the range from 450 to 500, if not every single student ID in the range of 101 to 500 is used and the array size is only 300
