Make a simple program that contains a main.c file and create multiple functions that takes an array of arbitrary length of numbers and adds them, calculates the average, and finds the standard deviation. Use $3$ different arrays $($size and values$)$ to calculate the average, standard deviation, and sum.

$./$main

the average is: x

the std is: x

the sum is: x

We will be creating a library from our lab assignment $1.$ Follow the notes in the lecture to convert your math functions, sum, standard deviation, and average to a custom library that will be linked in the linkage stage. We will also be adding a custom structure data type and a custom print function for the array. Detailed instructions are below.

Step $1$: Library creation

Create two files: statistics.h and statistics.c$.$ Statistics.h file will contain the funcion declarations. Stastics.c will contain the function implementation. Create a library of these two files that can be linked to$,$ i$.$e$.$ when you compile in this step it should look something like

gcc $-$o main main.c $-$lm $-$lstatistics

Ensure assigmment $1$ still operates as previously.

Step $2$: New functionality

Add the functions to your new statistics library to find the maximum and minimum of a given input array. Finally, find the absolute value of the difference between the maximum and minimum.

Next, create an output$\_$array.c and output$\_$array.h that defines a function which takes the array and size as an input argument and outputs the array. Output the array to the screen using the new function in main.c$.$ Compilation should look like this:

gcc $-$o main main.c output$\_$array.c $-$lm $-$lstatistics
