CSCI 112
Lab 3 - Simple C Functions

Solve a problem using a C Functions, Top-Down Design philosophy and proper Coding Conventions.

Read Chapter 3 in the Hanly/Koffman text. Also read related lecture notes (Top-Down Design with Functions).

Design and Write a program to solve Programming Project #5 on page 168 (p. 153 in the 6^th edition, p. 142 in the 5^th edition) of the Hanly/Koffman text. Use at least two functions wen creating your solution (one must be named: twoDecimalRnd, and another one: printMyResults)
Use redirection to enter your positive number with a fractional part. Do not prompt for these values, just read them in from a data file using scanf.

For your input, build a short data file (call it datain3) that includes only one float in the first line.
Suppose you wanted to enter 1.449. You would build a file datain3 that had the following number in line one.
1.449
Make sure to call this file "datain3" and save it to your directory.
A sample run of your program assuming "lab3" for the name of your run image would look like the following:
$ lab3 < datain3
A sample output would look like the following:
bbb1.449 rounded =bbbb1.450
(The b's are blanks)

The automatic submittal script will expect your output to be formatted exactly as shown above.
You do not need to submit your sample data file. I will provide a set of test data files for the automatic script to use to test your program.
Make sure to comment your code properly! Including the functions!
Follow proper Coding Conventions when programming.
