--Use Pipes--

Create a program in C where pipes are used. The program's execution line should indicate the number of children and the elements of an array that will compute their sums. The number of children can only be 1, 2, or 3.

Example for executing in linux terminal:

./program_name 3 1 2 4 5 6 7 (3 indicates the number of children, 1,2,4,5,6,7 is the array). With this input, it will assume the parent has pid 3, child 1 to have pid 4, and child 2 to have pid 5, and child 3 to have pid 6. Assuming this it will output the following:

I am the parent with pid: 3, sending the array: 1, 2, 4, 5, 6, 7

I am the child with pid: 4, adding the array 1, 2 and sending partial sum 3

I am the child with pid: 5, adding the array 4, 5 and sending partial sum 9

I am the child with pid: 6, adding the array 6, 7 and sending partial sum 13

I am the parent of pid 4, pid 5, and pid 6 and got the partial results 3, 9, 13 so final result is 25.

If the child size was 2, then each child instead would add 3 elements, or just 1 child would add all 6 elements of the array.

Another way of putting it

When I enter the single line: ./program_name 3 1 2 4 5 6 7 in the linux terminal to start my program, I want the "3" to indicate the number of children processes that can occur. The number of children can either be 1, 2, or 3. The "1 2 4 5 6 7" are just elements that will be put into an array. The array size can always be 6. After the command is entered, the following statements should be returned:

I am the parent with pid: 3, sending the array: 1, 2, 4, 5, 6, 7

I am the child with pid: 4, adding the array element's 1, 2 and sending their partial sum 3

I am the child with pid: 5, adding the array element's 4, 5 and sending their partial sum 9

I am the child with pid: 6, adding the array element's 6, 7 and sending their partial sum 13

I am the parent of pid 4, pid 5, and pid 6 and got the partial results 3, 9, 13 so the final result is 25.
