/*
 * Exercise 2-1.
 * Write a program to determine the ranges of char, short, int, and long
 * variables, both signed and unsigned, by printing appropriate values from
 * standard headers and by direct computation. Harder if you compute them:
 * determine the ranges of the various floating-point types.
