Question

****user comments: PLEASE READ INSTRUCTIONS THOROUGHLY AND KEEP THE STRUCTURE OF THE PROGRAM. JUST ADD THE ADDITIVES NEEDED
IN ORDER TO SUFFICE THE PROGRAM. PLEASE MAKE SURE IT IS IN C++ AND WORKS! THANK YOU!****

Write a program that uses a structure to store the following information for a particular month at the local airport:

Total number of planes that landed
Total number of planes that departed
Greatest number of planes that landed in a given day that month
Least number of planes that landed in a given day that month

The program should have an array of twelve structures to hold travel information for the entire year.
The program should prompt the user to enter data for each month.
Once all data is entered, the program should calculate and output the aver- age monthly number of landing planes,
the average monthly number of depart- ing planes, the total number of landing and departing planes for the year,
and the greatest and least number of planes that landed on any one day (and which month it occurred in).

};

const int MAXMONTH = 12;

int leastLandings = 99999; // Day of least landings
string monthMost; // Month that had most single day landings
string monthLeast; // Month that had least single day landings

//add for loop to count through array
//use a switch to determine month
