Airport Activity Problem

jonk8623 (7)
Hello I am fairly new to C++ and I am having a small issue with this project. The problem that I am having lies in the last part of the MAIN FUNCTION where I need to display the "greatest" and "least" planes landed in a single day out of a whole year. I have the correct number for the landings and the departures but I am struggling on getting what month of the year these two values occurred in. Here is the specifications for this part of the assignment.

• Largest number of planes that landed in a single day (in the entire year) and the month in which it occurred
• Smallest number of planes that landed in a single day (in the entire year) and the month in which it occurred

If anyone could lend some assistance that would be great.

Thank you I got the program working, but I am still getting a warning from the compiler stating:

warning C4715: 'displayMonth' : not all control paths return a value.

Any suggestions?

Never Mind I figured it out. Thank you for all your help.
