i have 4 threads. in each thread, there is a For loop. each thread is filling data in an array using that loop. now i want to update a progress bar based on the work these 4 threads are doing. how to do it? i thot of putting a global variable but the problem in that is each thread works randomly and will update that variable randomly. so the progress bar will go back and wont be smooth.

Each thread should increment the value of your global variable. Also, make sure to synchronize the access to such variable.

the sync is the main problem as there is no particular order in which threads to do that? so based on how much that array has been filled, i need to update the progress bar.
