copied!<p>For a homework assignment i need to program the following scenario. This is going to be done using semaphores using BACI (which is C--) </p> <p>There are 2 unisex restrooms that can hold 4 people each. Since it is unisex only people of the same sex can be in the restroom at the same time and FIFO is not important. I have the basic "algorithm" in my head to handle 4 men and 4 woman for 1 restroom. But i don't know how to code this. Any help would be greatly appreciated. Here is what I have.</p> <pre><code>Woman: Check to see if there are any men in the restroom. If so "wait". If no men check to see if there are 4 people. If so "wait". If no men and not 4 use restroom. When leaving signal there is a vacancy. If last woman signal the men if they are waiting if not signal the woman. Man: check to see if there are any woman in the restroom. if so "wait" If no woman check to see if there are 4 people. If so "wait". If no woman and not 4 use restroom. when leaving signal there is a vacancy. if last man signal the women if they are waiting if not signal the men. </code></pre> <p>These additional instructions were provided </p> <ul> <li><p>Use random FOR loops to simulate the passage of time in the appropriate places. This can be easily done by using a Delay function:</p> <pre><code>void Delay (void) { int i; int DelayTime; DelayTime = random (DELAY); for (i = 0; i < DelayTime; i++): } </code></pre></li> <li><p>where const int DELAY = some number from 10 to 100. </p></li> <li>Print and format output nicely and print messages in such a way that by reading the output, one can trace the execution order.</li> <li>Set the processes up to loop forever, and use control C (or control break) to stop your program.</li> </ul>
