• Compilation error since both a++ and b--

  should not be present in the iteration section (i.e after the second semicolon)

• a = 1

  b = 4

  a = 2

  b = 3

  a = 3

  b = 2

• a = 1

  b = 4

  a = 2

  b = 3

• Compilation error since both a = 1 and b = 4

  should not be present in the initialization section (i.e before the first semicolon)
