By default, C provides a great deal of power for formatting output The standard display function, printf, takes a "format string" that allows you to specify lots of information [flag][min width][precision][length modifier][conversion specifier]

C has no native string type; instead we use arrays of char If we omit the size of the array, but specify an initial set of characters, the printf statements

C strings are arrays of characters ending with a null-terminating character ''. Side note: use strlen to get the length of a string. Don't use sizeof!
