Slow down, young grasshopper. At 1-13, you're still a long way from functions, and even more so from using an IDE!

You have to write a program to read in a bunch of words, and then print a histogram of the length of those words. So first you'll need one loop to read the input. Since you want a histogram of the length of the words, you don't need to save the words, only their length. To save that, you need an integer array, and for an proper histogram a counter of the total number of words. How do you discern between one word an another? Let's simplify this and declare a word to be a series of letters between 'A' and 'Z' or between 'a' and 'z'. Anything else is a separator between words.

For output, loop over the array of word lengths you have. Calculate the percentage they take on the total number of words, and for that size create an appropriately sized "bar" using another, nested, loop.

Remember, the K&R book was written at a time when C programming was done with command line utilities, and all exercises can be done using nothing but an editor, a C compiler, and a command line debugger (eg. gdb).

NAME

       canadian-english - a list of English words

DESCRIPTION

       /usr/share/dict/canadian-english is an ASCII file which contains an alphabetic list of words, one per line.

FILES

       There  may  be  any  number  of	word lists in /usr/share/dict/.  /etc/dictionaries-common/words is a symbolic link to the currently-chosen
       /usr/share/dict/<language> file.  /usr/share/dict/words is a symbolic link to /etc/dictionaries-common/words, and  is  the  name  by  which
       other  software should refer to the system word list.  See select-default-wordlist(8) for more information, and/or to change the currently-
       chosen word list.

       The directory /usr/share/dict can contain word lists for many languages, with name of the language in English, e.g., /usr/share/dict/french
       and  /usr/share/dict/danish  contain respectively lists of French and Danish words if they exist.  Such lists should be coded using the ISO
       8859-1 character set encoding.

SEE ALSO

       ispell(1), select-default-wordlist(8), and the Filesystem Hierarchy Standard.

HISTORY

       The words lists are not specific, and may be generated from any number of sources.

       The system word list used to be /usr/dict/words.  For compatibility, software should check that location if /usr/share/dict/words does  not
       exist.

AUTHOR

       Word  lists  are  collected and maintained by various authors.  The Debian English word lists are built from the SCOWL (Spell- Checker Ori-
       ented Word Lists) package, whose upstream editor is Kevin Atkinson <kevina@users.sourceforge.net>.
