C++

Write a program to determine the average momentum of a collection of items with random velocities and masses. Do this using the following outline: 1. Construct a function named randVec that will take no arguments and return a dynamically allocated 3-element array of doubles. Each element in the array should be a randomly generated value in the range -100.0 through +100.0. 2. Using randVec and your momentum function from the previous part, generate momentum vectors for 1000 items, each of which has a random velocity (as described above) and a randomly generated mass in the range 1.0 through 10.0. Save the momentum vectors using a suitable array of pointers. 3. Determine and display the average momentum vector of the items using a for loop
