CMPU-235: Software Development Methodology

Homework #2

Due: Wednesday, Sept. 27

Modify both versions of your programs from Homework 1 as follows:

Add the ability to specify a command-line argument that is a file name. If not present, the program should work as before, reading data from the keyboard. If present, the program should read the data from a file of the following format:
```
       23 Michael Jordan
       19 Willis Reed
       24 Bill Bradley
```
... and so on.
After reading in the data, print out the list of players and their numbers sorted by number in ascending order, i.e. for the data above:
```
       19 Willis Reed
       23 Michael Jordan
       24 Bill Bradley
```
Take special care, this time, to ensure that your two programs are as similar as possible. One element of your grade for this assignment will be how independent your main code is from the data structure used to store the players. This includes using the same procedure names, variables, etc.

Note: Keep in mind that the easiest way to sort a list is as you read in values (i.e. to do an insertion sort on each element as it is added to the list). For arrays, on the other hand, the easiest way to sort is to read in all the values and then sort the whole thing. Think about how this affects your main program and your goal of making the two main programs as similar as possible.

The homeworks will be graded based on style, documentation, functionality, design, and the similarity of the data-structure independant portions.
