- Python: How do I format a number so that I get exactly 5 digits and then pad zeros after? I want to also round. I am reading a file and then writing those contents to another file. Original file: 1234.3092 1234.0 8912.32 I want just 6 digits so the new file should read 1234.31 1234.00 8912.32Write 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 1 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…Write a program to print your name 8 times using fork() IN VIRTUAL BOX LINUX name rohith
