Using the Star structure defined in the file pe07.cpp, write the function named starsBetween(). The function takes three input parameters: a vector of Star as well as a lower and upper bounds for the magnitude. The function selects only the stars whose magnitude falls between the two bounds (exclusive, not inclusive), and adds the names of those stars to the output parameter. The function returns a double representing the average magnitude of the stars selected. If no stars are in the range, then return -1. Here is an example of the function being called. vStars is the input parameter and names is the output parameter. vector names; double avg = starsBetween(vStars, names, 2.3, 2.4);
