Question
Write a C/C++ language program that creates an array of 10,000 random unsigned integers in the range 1 to 1,000,000. These integers are then stored in a text file called numbers.txt

Transcribed Image Text:Part 1: Write a c/C++ language program on Linux that creates an array of 10,000 random unsigned integers in the range 1 to 1,000,000. These integers are then
stored in a text file called numbers.txt
Part 2: Write a C/C++ language program on Linux that reads the file numbers.txt and checks each number for being a prime number. Only the prime numbers
from these are then written to a text file prime.txt.
Part 3: Modify the program of part 2 so that it takes an input argument num_jobs with a value between l and 8. E.g. if num_jobs is 3, it splits into 3 parallel
processes using fork() function and each process then calculates prime numbers from a subset of the input data. Together these 3 jobs find prime numbers
from all the 10,000 input integers. The overall parent process then combines the results from its children into a single file prime.txt
Part 4: Calculate the times taken by running the program of part 3, and make a table where the time taken for calculation is given for each value of num_jobs
from 1 to 8. A breakdown of the time should be given - file reading, prime number calculation, and file writing.
