Programming Assignment #$4$Chapter $7$ Synchronization Thread Safe Stack

The $C$ program stack$-$ptr$.$c $($provided$)$ contains an implementation of a stack using a linked list. An example of its use is as follows:This program currently has a race condition and is not appropriate for a concurent environment Using Pthreads mutex locks $($section $7\mathrm{.}3\mathrm{.}1),$ fix the race conditions. Test your now$-$thread$-$safe stack by creating $200$ concurent threads in main$0$ that intermix pushing and popping values.Use a loop in main$0$ to create all those threads. Apply all the things you ve leamed about creating and joining threads from previous chapters.Write one testStack function, and use it as the entry point for each thread.The testStack function should intermix $3$ push operations with $3$ pop operations in a loop that executes $500$ times.All threads use the same stack.gcc $-$pthread stack$-$ptr$.$c $-$o stack$-$ptr is an example command to compile and link your programIf you're up for it$,$ you may rewrite the provided C program into well$-$formed C$++$ code using proper Object Oriented Design concepts, but you must maintain the dynamically allocated linked list concept, and you must still use the Pthreads mutex locks.
