1. Suppose the number of distinct values of type float is 2^32.
   The number of values that lie in the interval (-1, 1) is closest
   to:

   a.  2                            b. 2 ^ 16

   c.  2^31


2. The number of bits in the Exponent component of an IEEE 32 bit float
   is

   a. 1                             b. 8

   c. 23                            d. 24


3. The fgetc() function

   a. reads at most one byte each   b. may read more than one byte
      time it is called                depending on the format code

   c. always consumes data until
      a newline is found.


4. The fgets() function

   a. reads a single byte from     b. always reads a specified number
      a file                          of bytes from a file

   c. stops reading when it finds  d. stops reading when it finds a
      a '\n' newline character or     null character or fills the
      fills the specified buffer      specified buffer space.
      space.

5. Suppose the fputs() function is called as follows:

   fputs(buf, stdout);

   Which best describes how the function will operate.

   a. A single byte stored at address    b. bytes commencing at address buf
      buf will be sent to stdout            will be sent to stdout until a
                                            \n (newline) character is found.
   c. bytes commencing at address buf
      will be sent to stdout until a
      NULL (binary 0) character is found.
