Write in C++

Alice is trying to monitor how much time she spends studying per week. She going through her logs, and wants to figure out which week she studied the least, her total time spent studying, and her average time spent studying per week. To help Alice work towards this goal, write three functions: min()total(), and average(). All three functions take two parameters: an array of doubles and the number of elements in the array. Then, they make the following computations:

  • min() - returns the minimum value in the array
  • sum() - returns the sum of all the values in the array
  • average() - returns the average of all the values in the array

You may assume that the array will be non-empty.

Function specifications:

Function 1: Finding the minimum hours studied

  • Name: min()
  • Parameters (Your function should accept these parameters IN THIS ORDER):
    • arr double: The input array containing Alice's study hours per week
    • arr_size int: The number of elements stored in the array
  • Return Value: double: The minimum value in the array

Function 2: Computing the total hours studied

  • Name: sum()
  • Parameters (Your function should accept these parameters IN THIS ORDER):
    • arr double: The input array containing Alice's study hours per week
    • arr_size int: The number of elements stored in the array
  • Return Value: double: The sum of all the values in the array

Function 3: Computing the median study hours

  • Name: average()
  • Parameters (Your function should accept these parameters IN THIS ORDER):
    • arr double: The input array containing Alice's study hours per week
    • arr_size int: The number of elements stored in the array
  • Return Value: double: The average of all the values in the array
