//Poll3
//This program enables the user to answer a 5 question poll about social consciousness issues.  The tallys are recorded and averaged.   
//After the user input portion, the program randomly generates tallies for a random number (from 5 to 13) of persons.  The program then
//averages all the tallies for each poll question and displays which  question had the greatest number of tallies.
