C Primer Plus®, Third Edition

Chapter 5

1. 1. 30

   2. 27 (not 3). (12 + 6)/(2*3) would give 3.

   3. x = 1, y = 1 (integer division)

   4. x = 3 (integer division) and y = 9

2. 1. 6 (reduces to 3 + 3.3)

   2. 52

   3. 0 (reduces to 0 * 22.0)

   4. 13 (reduces to 66.0 / 5 or 13.2, then assigned to int)

3. Line 0: Should include <stdio.h>.

   Line 3: Should end in a semicolon, not a comma.

   Line 6: The while statement sets up an infinite loop because the value of i remains 1 and is always less than 30. Presumably we meant to write while(i++ < 8).

   Lines 6–8: The indentation implies that we wanted lines 7 and 8 to form a block, but the lack of braces means that the while loop includes only line 7. Braces should be added.

   Line 7: Because 1 and i are both integers, the result of the division will be 1 when i is 1, and 0 for all larger values. ...
