/eed to add current x and current y to diffrentiate the two distances

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. Sample Input File "Data.txt" [edit] START 00 DATA 2424 DATA 424 DATA 4124 DATA 2512 DATA 00 STOP 195215 Sample Output [edit] Please Enter The Name of The Data File: Data.txt Final Location: (195.0,215.0) Total distance traveled 587.6 Distance to starting point 290.3 Average distance to start point =83.4 STUDENT OUTPUT: SOLUTION OUTPUT: Please Enter The Name of The Data File: BadFileName Please Enter The Name Of The Data File: BadFileName Error: File failed to open. Error: File failed to open. Please Enter The Name Of The Data File: proglla.txt Please Enter The Name Of The Data File: proglla.txt Final Location: (195.0,215.0) Total distance traveled 587.6 Final Location: (195.0,215.0) Distance to starting point 290.3 Total distance traveled 587.6 Average distance to start point 290.3 Distance to starting point 290.3 Average distance to start point =83.4
