Q1. Write the following functions: C++

a. A function that receives an array (type double) and initializes it with positive integers between 1 and 100.

b. A function that receives an array (type double) of positive numbers and returns the average of the elements in the array through a reference parameter.

c. A function that receives an array (type double) and prints its elements horizontally (on one line).

d. Write a main function in which you test the functions in parts a and b.

Declare an array of a certain size (of your choosing) in the main function then use the functions in parts (a,b,c) to initialize, compute average and print the array, then find the average of the numbers and print it. Submit code and as well as input and output of your program
