What to Hand In (see also: example project solution)

• A Program Organization Chart exhibiting the interactions between major program components. Attach a report to the chart providing a rationale for the program organization.
• A chart illustrating the major data structures your program uses, the transformations they undergo, and the components of your program responsible for these transformations
• A listing of the C program you write for your project, following the required standards.
• A session transcript in which compile and run your progrm to demonstrate its capabilities
• A printed copy of each of the files your program reads during the demonstration session.

Write a program that retrieves data from the file rainonly.dat (available on the Supplied Software page of the class web site), normalizes the data, and displays the normalized data on the screen.

• Data Format of rainonly.dat
  Heading Lines. There are no heading lines in the data file.
  Data Lines. Each subsequent line of the data file contains the rainfall amounts for each month in one year of a data collection period. The first number on the line gives the January rainfall, the second, the February rainfall, and so one through the twelfth number, which gives the December rainfall. The number of years in the data collection period, which you may assume is more than one and not more than 50, is the number of lines in the data file.
• Display Format
  Data Lines. Line up the numbers in columns, so that the normalized January rainfall figures for all years in the data collecction period line up in a vertical column down the screen, the February figures form another column, and so on through the December column.
• Data Normalization
  Normalize the columns of numbers in the data so that they all have unit standard deviation. That is, divide each of the numbers in the k-th column by the standard deviation of the numbers in the k-th column. (The k-th column consists of the k-th number from each of the data lines.)

Ground Rules

• Your program may assume that the input file contains rainfall figures for each of the twelve months in each year of the data collection period. That is, each line of the data file will contain exactly twelve numbers.
• Your program may assume that the data collection period is at least two years, but not more than fifty years. That is, the input file contains at least two and no more than fifty lines, each of which contains the monthly rainfall amounts for one year in the data collection period.
• Your program must not assume any specific value for the number of years in the data collection period.
• Your program must contain definitions of functions organized in modules, and it must make profitable use of them.
• Your program may use any aspects of C covered in class or in the assigned readings in the C textbook, but it must not use any aspects of C not covered in lectures or assigned readings.
• The Project Style Guide describes additional requirements.
