NOTE: It's a Operating System Project so Please use the POSIX linux library and do it in C Programming

Project Question:
1. You will implement two programs in this project that are closely related. The first program is called
ALU. This program accepts three arguments from the command line. Two arguments are numbers
while one argument is one of the operations from ‘+’, ‘-‘, ‘/’,’x’. Your main function should read
these arguments, if the number of arguments is not 3, then your program should return the value -9999
and exit. If number of arguments is 3, then your program should perform the operation between the
two numbers and return the result of the operation.
2. The second program is called CPU. This program will take 1 argument from the command line which
will be a filename. Your program should open this file and read mathematical operations from each
line. Each line of the file will have one number followed by an operation and then a second number. A
sample file is given below.
3 + 6
12 – 4
3 x 10
4 24
3. For each line in the file, your program should fork a child process, in the child process execute the
program ALU and pass it the three values that you read from this line as arguments. Once all lines
have been executed, you will wait for the child ALU processes to finish execution and read the return
values sent by these processes. You will output the result of the operations in a file called math.txt in
the following format
3 + 6 = 9
Page 2 of 2
12 – 4 = 8
3 x 10 = 30
4 24 = not enough arguments
Keep in mind that an operation might produce a floating point exception. For example the
following is not possible mathematically
6 / 0
For operations like this, your program should report the following in the math.txt file
6 / 0 = illegal operation
You should NOT check for the numbers to be zero. You should get the exit status from the “wait”
call and check if the program terminated due to an exception.
