Write a C++ program called
helps you match hangman or crossword-puzzle words.
Your program reads in a dictionary of words. The dictionary used in the sample run is here. It has the concept of a current “guess”, which is of a fixed length. Initially, all letters in the guess are undetermined, but some letters can be determined by the user.
% g++ wh.cc % ./a.out 'h' for help ? l 5 _____ has 0 matches. ? h l <len>: set length d <filename>: read a new dictionary a <letter> <positions>: add letter to the given positions w: show all words that match c: clear the guess to all underscores h: show this help listing q: quit _____ has 0 matches. ? d common-words.txt There are 4342 words. _____ has 687 matches. ? ae4 ____e has 150 matches. ? a t0 t___e has 12 matches. ? a h 1 th__e has 5 matches. ? w these those theme three there th__e has 5 matches. ? ae2 the_e has 3 matches. ? w these theme there the_e has 3 matches. ? r Invalid command! the_e has 3 matches. ? c _____ has 687 matches. ? q
ccommand were given.
lcommand is given, except as shown in the example above.
acommand are a space-separated list of integers.
acommand says <letter>, it means one letter a-z or A-Z.
.eof()method will result in the loss of several points.
grepwould make this too easy.
If you have any questions about the requirements, ask. In the real world, your programming tasks will almost always be vague and incompletely specified. Same here.
