Add 50 more 'rookieArtists' threads that paint. You may initialize their paint colors and starting positions randomly in a for-loop.
Artists should not have the same color (Think about what this would mean when debugging!)
Each artist has also agreed that they will not paint over each others work (the artists do respect each other--even the rookies). This means you need to enforce some locking mechanism.
I suggest using a 'trylock'
An example is provided under trylock. c
There should be no deadlock in this program.
Note: Care should be taken to minimize and only put locks around code that needs to be protected.
Locals in threads for example, do not need to be locked if they are not shared.
All of the artists should congregate (i. e. join) at the end of the program to admire their work.
You should output an image called "canvas. ppm" at the end of the program.
You may reference code from previous labs/assignments to understand the PPM format.
