Question

Find Largest and Smallest Number Firstly, manually create a file Numbers.txtand fill it with integers, one below the other. Write a program that reads ANY sequence of integers (can be positive, 0 or negative) from this file. Using a looping construct, you will read numbers from the file till end of the file is reached. Calculate the largest and the smallest numbers among the data in the file. Your code must display both of those on the terminal screen along with total count of numbers present in the sequence and the average (always print two digits after decimal point) of all numbers in the file.
