Your program should perform an operating system API call to open a text file named Data.txt$,$ write $1,000,000$ random

numbers in the range $[0.\mathrm{.}100]$ to the file, and close the file. Next, the program creates three threads. Each thread should:

$1.$ Perform an operating system API call to open the Data.txt file.

$2.$ Create a file named Data$\_$Thread$\_$X$.$txt$,$ where X is the letter A$,$ B$,$ or C$,$ depending on which thread created the file.

$3.$ Each thread copies the data from the Data.txt file to its Data$\_$Thread$\_$X$.$txt file.

$4.$ While copying the data, calculate the average of the numbers in the Data.txt file to two places past the decimal

point $($e$.$g$.,50\mathrm{.}00)$ and output the average just before the thread finishes. Make sure this works on files of any size.

$5.$ Close the Data.txt file and the Data$\_$Thread$\_$X$.$txt files.

$6.$ Compute each thread$$s execution time and output it in milliseconds $($ms$).$

$7.$ The main thread should wait for the thread tasks to finish. The main thread should also compute the total $$wall

clock$$ execution time $($ms$)$ of the program execution $($including all three thread tasks$)$ and output the result.

$8.$ Be sure it is clear which thread is outputting which information in #$4,$ #$6,$ and #$7$ above
