we have the following components for our c program $(1)$ struct variable $(2)$ functiontofindprime $(3)$ thread function $(4)$ main function $.$ In this program our task is to read prime numbers from a file on our local disk which is full of numbers and determine whether the number is a prime number or not a prime number. Our function to prime numbers has the logic and workings to find the prime numbers and our thread function calls this function and finally sends the prime count and the prime numbers themselves to the main function to be executed there.
