Question

C++ programming

Program 1:

Write a program that uses a structure to store the following weather data for a particular month:

Total Rainfall

High Temperature

Low Temperature

Average Temperature

The program should have an array of 12 structures to hold weather data for an entire year. When the program runs, it should ask the user to enter data for each month (the avg temperature should be calculated.) Once the data are entered for all the months, the program should calculate and display the average monthly rainfall, the total rainfall for the year, the highest and lowest temperatures for the year (and the months they occurred in), and the average of all the monthly average temperatures.

Input validation: only accept temperatures within the range between -100 and +140 degrees Fahrenheit.

Program 2:

Modify your program so it defines an enumerated data type with enumerators for the months (JANUARY, FEBRUARY, etc.). The program should use the enumerated type to step through the elements of the array.

User interface is important!

You should post pseudocode

Your code should have appropriate comments

Your code should be well-formatted, with camel case variables

Variables should be self-descriptive

Your code should have functions (besides main!)

Your functions should only do one thing
