I'm taking an independent study course on C++ programming through my college. So far I've created a mean and standard deviation program, a linear regression program, and a few other much simpler programs. I am now working on a program to add up to 12 vectors together, and am having a lot of trouble with it. If anyone could help me find an example C++ vector addition program to use as a template, it would be greatly appretiated. Thanks a lot.

A milling machine which weights 120KN is vibrating within the frequency of 20 Hz to 40 Hz due to an unbalanced mass.
(a) The laboratory has an accelerometer with a natural frequency of Wn = 100 rad/s. Determine if the accelerometer is suitable for measuring the acceleration of the milling machine vibration if the measurment error is to be less than 5%.
(b) The shop floor wants to isolate the vibration from the milling machine to yhe ground. The required transmissibility ratio TR is 0.3 at 30 Hz using an isolator that has a stiffness of K=50000000 N/m. Find the damping ratio of the isolator.
