Problem 2. Read Section 2.1 of the textbook. The C type char is used to hold characters; the C language specification says that a variable of type char is always stored in a single byte (8 bits). a. How many distinct character values can be represented by a variable of type char? b. A character set is a mapping between glyphs (i.e., symbols, like ' A ' or ' $ ') and integers. Most programs in C use the ASCII character set. How many characters are in the ASCII character set? (Hint: man ascii) c. Some languages use many more symbols than English or other European languages-Chinese, for example, uses thousands of symbols in its written language. How might C provide support for programs that need to represent symbols from such languages? (Hint: search the web for "wide character".)
