/*
Assume that there is a function `toupper' which takes a char argument.
It returns the uppercase version of its argument if the argument was a
lowercase letter; otherwise it returns its argument. That is,
toupper('c') returns 'C'; toupper('F') returns 'F', and toupper('#')
returns '#'.  Write a program which reads its input, translates the
lowercase letters in the input to uppercase, and writes out the result.
Your program should terminate when it sees EOF.
