Write a program that creates multiple worker threads to calculate the sum of float point values saved in a file. each thread calculates a partial sum, and the main thread adds up the partial sums. your program will read the float point values from a file and print out the sum on the screen. the number of worker threads, as well as the file containing the float point values, are specified in the command line. for example. problem_1 4 ./file_containing_values you may use gendata. c attached with the assignment to generate the file. your main thread can memory-map the file, such that the worker threads can access the float point values in the file easily.
