The purpose of Homework 1 is brushing up C++ skills and warming up for future programming assignments. Vectors are not allowed. Linkedlist in C++ library should not be used. The program has the following functionality: 1. Once it starts, it asks the user to type the input file name (a txt file). The print out information must be: Please input the filename: 2. The program uses the file name to open the file. The file has a number of lines. Each line has two numbers separated by a comma. Therefore, there are actually two columns of numbers. For example: 312312, 56877 2267, 3698 3, 3478 87907, 768 3. The program processes the input data to calculate the average value of all valid numbers in the first column and the largest value of all valid numbers in the second column. The print out should be The average value of all numbers in the first column: XXX.XXXX The largest value of all numbers in the second column: XXXXX The total number of rows in the file is: XXXX The invalid numbers are: XXX, XXX, XXX, ... Requirements: 1. [will be 0 if it does not compile or crash when it starts] The homework must be done in C++ and compatible to C++11. A brief readme.txt file about how to compile using g++ in command line should be provided. Your submission must be in a .zip or .tar.gz file. 2. [5%] The Following identification information must be included at the beginning of your cpp file. //Name: XXXXXXX //NetID: ab1234 //Email: XXXX@csueastbay.edu 3. [5%] The output average value should retain 4 decimal digits. 4. [10%] The program must use cin and cout to deal with command line input and output. 5. [10%] The program must ask user to input again without crashing file name is invalid. 6. [10%] You can only use array (no vectors, no linked list, actually you also can do it without array...) to solve this. 7. [30%] Students must implement loops by themselves to calculate the average and to find the largest value, invalid numbers, and number of rows.

8. [30%] There are invalid numbers (like 1P24...) in the input data file, make sure those numbers will be recognized and abandoned automatically by your program without crashing.
