Devise a program that counts the number of characters in its input up to the end of file
Well, it doesn't do much. But it is not bad. A few issues:


main() should have parameters
excess blank lines (lines 5, 12, 16, 18) spoil the appearance
no \n on the last printf
the spec doesn't say 'printable' characters, just characters.
"please" needs a capital p and "resault" should be "result"
