In this lab you simulate one of the classica synchronization problenms in órder tð see how the (semi) critical section problem could be implemented using binary and counting semaphores. 5 processes are characterized by 3 readers and 2 writers. Up to two reader processes can be inside their critical section without any writer process. For writer process to go into its critical section, it should check whether there is any reader or writer process is in the critical section. Critical section in this problem is reading shared data buffer for reader processes and updating shared data buffer for writer processes. It is optional to implement real shared data for readers and writers, but you have to specify clearly following things in your sample output. • When reader or writer process enters its critical section, it has to report whether there are any

The semantics of a call to a “simple” subprogram requires the following actions: A. Save the execution status of the current program unit. B. Compute and pass the parameters. C. Pass the return address to the called. D. Transfer control to the called. E. All of the above

Please I need to answers these questions in C++. Thank you. Question: Does the if-else if structure offer any advantages over nested if statements? Choose the correct answer from below: A. It helps keep the code understandable and readable on the screen or on paper B. It does away with the need of a trailing else C. It can handle logic that nested if statements cannot handle D. Neither has an advantage over the other E. The text did not discuss this topic   Question: What is the purpose of a trailing else in an if-else if ladder structure? Choose the correct answer from below: A. It handles the "none of the above" situation in the problem B. Two of the other answers are correct C. It is often used to catch errors D. It deals with the most complex boolean expression  E. It is the only part of the ladder that is not optional

Execute according to the following guidelines: Create a new C program that supports the following capabilities: Variable declarations (you need to research variables, declarations, and data types). Getting input from a user (you need to research the scanf() function). Operators (you need to research the operators available in C). Printing formatted output (you need to research the scanf() function).
