Write a function that outputs a vector of doubles with each number in the vector separated by a space then a newline after the entire vector is output. The whole vector output should be preceded by a single line saying "Current Vector Contents:".
Write a function that takes a vector a doubles and reverses the order of all the elements of the vector.
Write a function that fills a vector of doubles with positive numbers using the standard input stream cin, terminate the input when the user enters any negative number. A single output prompt should precede the initial input stating directions for user.
Write a main function that creates an empty vector, calls functions from 2 & 3 and calls your output function before and after each of your calls to 2 and 3.
