Using C++.

In the class the implementation of the readers-writers problem using SDL threads has been presented. However, the read and write tasks of the reader thread and the writer thread are not given. Implement these tasks as reading and writing of a file named counter.txt, which contains an integer counter. A reader thread reads the counter from the file, and prints out its thread name and the value of the counter. A writer thread increments the value of the counter in the file, prints out its thread name and the new value of the counter. Each thread repeats its task indefinitely in a random amount of time between 0 and 3000 ms. Your main program should create 20 reader threads and 3 writer threads
