Question

Write a C/C++ program that takes an input (array) from 1 to n (say n = 50) and displays the string representations of those numbers with following conditions

If the current number is divisible by 2, then print CSU

If the current number is divisible by 5, then print LB

If the current number is divisible by both 2 and 5, then print CSULB

If the number is neither divisible by 2 nor 5, then print the number

Example: 1 CSU 3 CSU LB CSU 7 CSU 9 CSULB 11 CSU 13 CSU LB CSU 17 CSU 19 CSULB …

Tasks to do:

(4%) Implement the solution using a single thread (i.e., without using threads and only a main function with any other possible helper function for ease) with all the above conditions implemented in the correct order so that the results are correct. Reason about what can cause the algorithm to print unwanted results (think about the order in which you will write the above conditions). Provide your reasoning about the correct order and the result using single threaded application.
(4%) Implement a synchronized multithreaded version of CSULB with four threads. The same instance of CSULB (array of 1 to 50) will be passed to four different threads:

Thread 1 should call csu() to check if divisible by 2 then print CSU.
Thread 2 should call lb() to check if divisible by 5 then print LB.
Thread 3 should call csulb() to check if divisible by 2 and 5 then output CSULB.
Thread 4 should call number() which should only print the numbers.
