14.2.15 String Input Conversions
--------------------------------
This section describes the ‘scanf’ input conversions for reading string
and character values: ‘%s’ and ‘%c’.
The ‘%c’ conversion is the simplest: it matches a fixed number of
characters, always. The maximum field with says how many characters to
read; if you don’t specify the maximum, the default is 1. This
conversion does not skip over initial whitespace characters. It reads
precisely the next N characters, and fails if it cannot get that many.
The ‘%s’ conversion matches a string of non-whitespace characters.
It skips and discards initial whitespace, but stops when it encounters
more whitespace after having read something.
For example, reading the input:
hello, world
with the conversion ‘%10c’ produces " hello, wo", but reading the same
input with the conversion ‘%10s’ produces "hello,".
