CenTable - Requirements Specification CenTable is a system for creating tabular reports from county-level U.S.Census Data it is appropriate for batch processing (both off Ine and in support of an on-line system). The inputs to the system are the ASCII county data fle (land associated data dictionary) and an ASCI tle that describes the tabular report to be created. The output is a table in either HTMI or AScll text format 1. Command-Line Parameters 1.1. The first command line parameter must be the mame of the county level data file to use. 1.2 The second parameter must be either-h (to indicate that the output should be in HTMor (to indicate that the output should be in ASCl et) Location of \"Files\" .1.

Solution
Okay So basically what you have to create a C Program for an application. This should be called
CenTable.
Input:
1. This system will take as input a text file which contains information about countries and their
census. It must be containing a lot of fields. You need to once take a look at the file to

2. understand what format it is in and create your program accordingly.
2. The next input is a commnd line argument which would be given while running the program.
This would be the name of the new file your program will create as an output.
3. Another input will be again a command line argument that is either -h or -t where -h indicates
that your program will generate a HTML file and -t indicates that your program generates a text
file.
Processing:
What you have to do is,
1. Read the input file. Have different array variables that will strore different fields provided in
the file in the same order.
2. Have two functions - one for HTML file creation and one for text file creation.
3. In HTML file creation function, have your standard out to first add the header, body and table
heading tags. Then have a loop to add each and every row of the table with data. Also provide
the attributes for table (aligment). Dont forget to name this file with the extension .html
4. In text file creation function, use standard output to do the same job as above but the spacing
and formatting must be hardcoded. i.e you have to provide dashes(-) to provide table borders.
Name this file with .txt extension.
Output:
Either a html file or a txt file that will contain tables regarding census information for all the
countries.
