(Optional)

3. It is define as : virtual int myfunction() = 0;
4. A class is "abstract class" when it has at least one
pure virtual function.
5. You cann't create instance of "abstract class", rather
you have to inherit the "abstract class" and overload all
pure virtual function.

Write a program to read the data and evaluate the results of the election. Print all output to the screen. Your output should specify: The total number of votes, the number of valid votes and the number of spoilt votes. The winner(s) of the election. Hint: An appropriate search should be used to determine the winner(s). The votes obtained by each candidate sorted in terms of the number of votes obtained.
