There is a text file containing the texts. The sentences in this file can be accessed in a random

access way. $($If there is no such file, create it yourself$)($The size of the file must be large enough$).$ A

total of $12$ threads will run in the system. $8$ Threads will be producer threads and $4$ threads will be

consumer threads. Each consumer thread has a queue structure that holds sentences. $8$ producer

threads will read the sentences from the file and assign them to the queue structure of the

consumer threads. Consumer threads will find the number of characters and words in each

sentence. At the end of the program, the number of words and characters in the text file will be

written on the screen. $($It is better to write which each thread does how much work.$)$
