Write in C++

Input.txt file will have any numbers and code will output another text file with prefix sum of the array

Write easy program with multiple processes.

this is as clear as I can get... specify in which aspect you need clarity.

Given an integer array of size n denoted A[O...n - 1], the prefix sum problems involve computing another integer array B, also of size n, satisfying the following property: Hi :0 : name of the text file that contains n integers representing the input array A Zoutput-file>: name of the text file that contains n integers representing the output array B (to be computed by your program) m: number of processes that will perform the work (degree of concurrency) If the input file does not contain exactly n integers (separated by white space), then your program should terminate with an appropriate message. Your program should be able to handle the cases when m does not divide n evenly and when m : name of the text file that contains n integers representing the input array A Zoutput-file>: name of the text file that contains n integers representing the output array B (to be computed by your program) m: number of processes that will perform the work (degree of concurrency) If the input file does not contain exactly n integers (separated by white space), then your program should terminate with an appropriate message. Your program should be able to handle the cases when m does not divide n evenly and when m <.><.>
