Function Documentation

std::string getWord

(

std::istream &

in

)

Reads a word from input stream in, where a word is the longest possible sequence of alphabetical characters. Reads (and ignores) one non-alphabetic character at the end of the word.

Returns

The word at the start of the input. (This will be the empty string if the input does not start with an alphabetic character.)

Remarks

Only handles words with alphabetic characters; does not skip leading whitespace; returning the empty string is a hacky way of reporting that no word was found.
