CS 2401 Assignment #2

Objective: The goal of this assignment is to practice using 2-dimensional arrays.

Background: To study climate change in El Paso area, UTEP students record the temperature and the wind speed at different locations within the city on different days. Temperature measurements are placed in a file, each line corresponding to one day of measurements, in each line we first place measurements from the 0-th location (temperature first), then measurements at the 1st location, etc.

Example. A file

68.0 5.2 71.0 6.3
66.5 3.1 69.5 4.9

• On Day 0:
  • at Location 0, we had temperature 68.0 and wind speed 5.2;
  • at Location 1, we had temperature 71.0 and wind speed 6.3.
• On Day 1:
  • at Location 0, we had temperature 66.5 and wind speed 3.1;
  • at Location 1, we had temperature 69.5 and wind speed 4.9.

Assignment: Write a program that, first, stores the measurement results (which are originally given in a file) in two two-dimensional arrays: the temperature array and the wind speed array. Your program should include the following methods:

• a method that fills in the arrays from a given file;
• a method that, given a location, returns the average temperature at this location;
• a method that, given a location, returns the average wind speed at this location;
• a method that, given a day, returns the average temperature on this day;
• a method that, given a day, returns the average wind speed on this day;
• a method that returns an average temperature over all days and all locations;
• a method that returns an average wind speed over all days and all locations;
• a method that, given a day, returns the location which was the warmest on this day;
• a method that, given a location, returns the day on which this location was the warmest;
• a method that returns the highest temperature at all locations on all days.
