Please help fix my average distance to start "distanceToStart" calculation. please look at sam[ple output for example of intended output. my current calculation is "distanceToStart = sqrt(pow(startx - backx, 2) + pow(starty-backy, 2));". please correct to give average distance to start.

Write a C++ program that will process a stream of GPS data. Each line of data starts with a command, followed by the data for that command. There will be one command per line. Your program should. 1. Ask the user to enter the GPS data file name. " "Please Enter The Name Of The Data File: " - Echo print the file name. - If the file does not open 1. "print an error message - return to step 1 2. Skip the first 2 lines of the data file 3. Process each command in the data file 4. Report the following to the screen (cout): - Final Location - Total distance traveled (rounded to one decimal place) - The Final distance to start point (rounded to one decimal place) - Average distance from the start point - Commands: - START - indicates the starting location of the trip - STOP - indicates the ending location of the trip - DATA - indicates a turning point. Assume [edit] 1. All coordinates are in a two dimension cartesian coordinate plane. 2. All numerical output should be rounded to 1 decimal places.
