The document discusses the character set of the C programming language. It states that the character set includes letters, digits, special characters, and empty space characters that can be combined to form commands, expressions, and other tokens for C programs. Letters consist of the 26 English alphabet letters and are case sensitive. Digits include the numbers 0 through 9. Special characters include various punctuation symbols. Empty space characters include spaces, tabs, carriage returns and newlines.
