Please write a program in C++ that will read in a list of numbers from a file (which will be named as a command line argument), and output the top three numbers to stdout in sorted order, highest to lowest. The numbers will all be positive integers. A given input file will contain at least 3 and at most 25 numbers. In addition, please write this program in simpler functions if possible such as booleans, while loops, for loops, or if statements. Thanks!
