I need some help with my C programing I have code started bu

I need some help with my C programing. I have code started, but am stuck on more difficult concepts.

Task:

Write a program that reads from ds4rd.exe (document your command line options that you use when running ds4rd.exe) and outputs the given x, y, and z gyroscope values followed by the moving averages of x, y, and z. It should also output the maximum and minimum values from the array used to compute the averages, which are calculated in a maxmin function. The output should be all on one line and separated by commas.

The length of the moving average shall be given on the command line to your program (code is included in the sample to help you read this input). Once enough data has been read to output a moving average, a new output should be generated for each input line. Your program should end when the SQUARE button is pressed.

Code:

Thank you so much!

Solution

#include <stdio.h>

#define MAXPOINTS 10000

// compute the average of the first num_items of buffer
double avg(double buffer[], int num_items);

//update the max and min of the first num_items of array
void maxmin(double array[], int num_items, double* max, double* min);

//shift length-1 elements of the buffer to the left and put the
//new_item on the right.
void updatebuffer(double buffer[], int length, double new_item);

int main(int argc, char* argv[]) {
  
   /* DO NOT CHANGE THIS PART OF THE CODE */
