Part 1:

Use functions to write a program that asks the user to enter an items cost and its markup percentage. It should then display the price. The program should have a function that receives cost and markup percentage as arguments and calculates and returns the price of the item. Use a function to calculate the cost.

Part 2:

Continue the above program and add the following: add a function to read file input that will contain a while-loop that reads an unknown number of integers from the file input.txt and assume one integer per line. As you read the file using a while-loop, count the number of integers in the file and return the number to the main function (return count) where you will print the total and average to the screen.
