Introduces character strings
Uses type coersion, shows float to int
Examples of functions
/*This introduces the idea of a string of characters -- used to store words.
It introduces gets() to read a string and the specifier %s to print them
/* the book gives this as an example of saving time with a typecast
On Example 1 page 115 he says that the first loop -- with typecast
should run faster that the second loop -- running the loop with a double variable
He is right, but is it enough to care about?
Remember the time is probably accurate only to the nearest second.
