Lab Assignment for operating system

Lab Assignment 1: Finish the below tasks using the language and the programming environment of your choice. (Due on June 30, 2013 11:59pm) 1. Design and implement “lock” and “condition” variables. You may either use semaphore as a building block, or you may use more primitive thread routines. When you write the description of your implementation, explain and justify your design. The skeleton code (pseudo code) below is for illustration purpose only (it is incomplete and may contain errors; correct it by yourself). You can provide your own solution without using any code structure in the skeleton code as well. Find it in the attachment.
