A file named realnumbers.txt contains a lot of floating point numbers, each with a whole number and fractional part.  The numbers may be positive or negative; but all have a decimal point and at least one digit on either side of it.   Some lines have a single number; some lines have several with one or more spaces between each two numbers.  The number of values in this file is not known; however, the file contains fewer than 30,000 bytes.

You are to write a MIPS assembly language program that reads a file such as realnumbers.txt and displays several items of information about the values in it:

• how many numbers there are,
• the sum of the negative values,
• the sum of the positive values,
• the most positive number
• and the most negative number.

Your program should prompt for the file name and then open whatever file is specified.  In this way, you can create your own small file of numbers to test your program on.  When you test-run the program, enter your sample data file name.  When you get the program working, then run it and enter realnumbers.txt as the file name.

You can get a copy of realnumbers.txt from the I:\ drive at I:\jlwolfe\300\fall05\realnumbers.txt or from the P:\ drive at P:\courses\fall05\cosc\cosc300\001\information\realnumbers.txt  or from WebCT under Class Handouts, Project #4

Hand in a printout of your well-documented program and a printout of the program's output.  Capture the output in the log file, paste the register section and console section into a Notepad file and print it.  You can also use Notepad to print the program.  Make sure the printout does NOT have lines that wrap.  It is nearly impossible to read an assembly language listing which is full of wrapped lines.  Also, copy your .s file to the handin folder on the P: drive.  You should name the file after yourself before copying to the handin folder.
