Dynamic Array Question in C++?

Write a program using dynamic arrays that asks the user for the number of candidates in a local election, and then creates the appropriate ar rays to hold the data. The program then asks the user to enter the last name of each candidate and the number of votes received by her/him. The program then outputs each candidate’s last name, the number of votes received and the percentage of the total votes received by the candidate. Finally, it also outputs the winner of the election.

======================================...


DISCLAIMERS:


(a) Code does not handle the case where user enters multiple winners, i.e., more than one candidate has the highest number of votes - do it yourself.





(b) Code does not handle the case where multiple candidates have same last names. Right now, they are undistinguishable. To resolve this, you have to add a "number" feature being printed - do it yourself.





(c) Code will need some #include headers to compile. stdio.h, stdlib.h, iostream.h etc basic ones I can think of. The getc() at the end I think needs ctype.h. Resolve such errors youself.
