1. Write a program that reads PAIRS of integers from the standard
   input.  The program should print the number of pairs whose sum
   is 20 to the standard output.


2. Write a program reads integer values from the standard input
   into an array of 20 ints (you may assume that there will never
   be more than 20 items in the input) and then prints them out in
   the reverse order in which they were read (you may NOT assume
   there will be exactly 20 items in the input file).

3. Write a program that reads character values from the standard
   input using the %c format code until end of file is encoutered.
   The program should then print the number of upper case
   alphabetic characters that were read.
