Develop a C++ function with following function prototype: double fileAvg (string fname); The function accepts the name of file as input and returns the average of the numbers in that file (the file is assumed to contain numbers only). Write a C++ main program that prompts the user to enter a file name that contains a set of numbers. The main program should calculate the average of the numbers in the file using the function fileAvg and display the returned value to the user.
