This is a question that is asked in various exams of object oriented programming and it is implemented in c++

|   An election is contested by five candidates.                                                                    |
|   The candidates are numbered 1 to 5 and the voting is done by marking the candidate number on the ballot paper.  |
|    Write a program to read the ballots and counts                                                                 |

|   In case, a number read is outside the range 1 to 5, the ballot should be considered as a 'spoilt ballot'        |
|   and the program should also count the number of spoilt ballots.                                                 |
