Divide and Conquer
==================
Described in one phrase, the histogram project is daunting; but divided
into numerous small steps, each of which we can take one at a time, the
project becomes less fearsome. Let us consider what the steps must be:
• First, write a function to count the words in one definition. This
includes the problem of handling symbols as well as words.
• Second, write a function to list the number of words in each
function in a file. This function can use the
‘count-words-in-defun’ function.
• Third, write a function to list the number of words in each
function in each of several files. This entails automatically
finding the various files, switching to them, and counting the
words in the definitions within them.
• Fourth, write a function to convert the list of numbers that we
created in step three to a form that will be suitable for printing
as a graph.
• Fifth, write a function to print the results as a graph.
This is quite a project! But if we take each step slowly, it will
not be difficult.
