Assignment Help:
You must use fork and pipe to complete this project.

This project creates processes to add all numbers in a file. The user will enter a number (1, 2, or 4) of parallel processes to create for processing the numbers. The system will then create this many processes, evenly dividing the file contents between the processes. For example, if the file has 1000 numbers and the user wants 4 processes, then each process would process 250 numbers in the file.

III. System Description

The system is illustrated in the diagram shown below. The processes are as follows:
1. Parent process. This process allows user to input the number of processes to create (1, 2, or 4). It determines what portion of the file each process must work on and informs the process via a pipe. It then waits for each child to report its result. Once each result is received, it combines the results prints the overall result.
2. Child process. Receive which part of the file to process. Process the file and send results back to the parent process.
