Question

For this programming assignment, you will develop a program that will analyze the monthly closing stock prices for five (5) companies in 2015. The stock price data for these companies will be provided in an input file named stocks.txt, which includes the company's name and the closing stock prices for each month. You will use a total of three(3) arrays: (1) a one- dimensional array to store the companies' names; (2) a (parallel) two-dimensional array to store the monthly closing stock prices; and (3) a (parallel) two-dimensional array to store the quarterly averages for closing stock prices. Your program must contain at least the following functions: a function to read and store data into two of the arrays a function to calculate and display the companies with the highest and lowest monthly averages a function to calculate, store, and display the quarter averages for all companies Any function that needs to "store" data should write to an output file (named .txt). Successful completion of this assignment includes (but is no limited to): Use of 1-D and 2-D arrays Properly named .cpp and .txt files Inclusion of the algorithm used to develop your program as comments within your program A program that compiles and executes properly with an input file A program that properly computes and displays the outputs listed above
