Answer to Question #197374 in C for Arunan Naicker

Question

Exercise 2 : Mining Temperature Data

The highs and lows of the 3 first weeks of 2020 temperature data are available on a piece paper and we have decided to store

them in a three-dimensional array in which the first index represents the 3 first weeks of the year, and take the value from 0 to

2; the second index is numbered 0 through 6 and represents the days of the week, and the last index which is numbered 0 and

1, represents the day’s high and low temperatures, respectively.

(2.1) Write a C program that enables you to capture the 3 first weeks of 2020 temperature data, from the keyboard, and store

them in the array described above. You must check the validity of any data entered.

(2.2) Write functions to request the following:

(a) Any day’s high and low temperature

(b) Average high and low temperature for given week

(c) Week and day with the highest temperature

(d) Week and day with the lowest temperature

(2.3) Write a driver program to test your functions defined in (2.1) and (2.2).
