Input file numbers.txt has
19 69 43 15 23 89 19 54 69 4 13 37 66 8 78 67 32 76 13 87 42 23 32 88 21 4 2 61 99 43

question is ;

Write a program that reads in an array of type int. It provides facility to either read an array from the keyboard or from a file, at the user's choice. If the user chooses file input, the program should request a file name. You may assume that there are fewer than 100 entries in this array. Your program determines how many entries there are. In addition, the program should also find the maximum number in the array and calculates the average of the array. You are required to use functions.

if its not working, please fix it.
