Hello Chegg!

I am working on a project to write a parallel program that will run N threads that can sum an array of 100000 elements. those elements come from an array.txt file. I have attached my current work so far.

If you can help me figure out how to get this code to work for when N = 1, 4 and 8 that would be appreciated with a like.

in the image i attached the correct sum is given when N=1 but the other values are incorrect. the answer should be -5762.213221.
