Part A: Parents, Children and Threads $(55$ marks$)$

PART A$\mathrm{.}1.(30$ marks: $5$ for Phase $1$ and $5$ for Phase $2$ and $20$ for Phase $3)$ Write a WINDOWS program that creates multiple threads that each perform the same function $($compute squares of positive integers$)$ in parallel until a deadline, without synchronization between the processes$/$threads of any kind. The number of child threads $($threads$)$ and the deadline $($deadline$)$ and the maximum integer $($size$)$ are to be command$-$line parameters. Each thread does the same task. The task is given below which utilizes the third command$-$line parameter $($size$).$ The usage is as follows: $./$partA$1$ threads deadline size.

Parent thread functionality:

The application should have a parent thread create M child threads.

The parent should then sleep until the deadline. The simplest way to do this is to use the system call Sleep.

If the deadline occurs before all children complete, inform the child threads that they should exit. One possible strategy is if the deadline has passed, the parent sets a global variable named something like keepRunning to have the value FALSE. The child threads would read this variable each time Square$()$ is called from the main loop of the thread that calls Square$().$ If you find some other way to do this, you may do so$.$ Please document your solution carefully.
