Program: Write a C program that uses the following double array: double userdatal5] -2.1, -5.9, 4.7,8.9, -3.0 The program will call a function named: array_avg that takes the array and number of array elements as input and returns the average (as a double). The function should be general enough to work for a double type array of any size. The main() function then displays the result to 2 decimal places For partial credit (-4 points), this can all be done within main) instead of as a function. Suggestion: Get the program to work all within main) initially, then move that code into its own function. The program is to run gracefully with clearly-labeled inputs and outputs and the code should be easy to follow (comments, etc.). If needed, the average is the sum of all values divided by the number of values
