Question
What would be the missing Line code?
The program first reads integer participantCount from input, representing the number of pairs of inputs to be read. Each pair has
a string and an integer. One Participant object is created for each pair and added to vector participantList. Output "Average
participant age: " followed by the average age of all the Participant objects.
Ex: If the input is:
5
Ken 53 Huy 61 Gil 80 Ben 57 Kai 25
then the output is:
Average participant age: 55.2
Note: The vector has at least one element.
