2
Total Number of Operations

• In order to calculate the number of operations,
  the Software Engineer must do the following,
• Obtain the Classes CRC index cards.
• Count the number of operations listed for the
  class.
• Input this number into the cell.

3
Number of Operations Overridden by a Subclass

• If this particular class is a subclass of another
  parent class, it may over ride some operations of
  its parents class.
• To calculate this, the Software Engineer must do
  the following,
• Obtain the CRC index cards for both the subclass
  and parent class.
• Pick a particular operation and see if it is
  overridden in the subclass.
• If so, add one and continue on to the next
  operation.
• Else, proceed to the next operation
• Continue until all operations have been
  processed.
• Record value in cell.

4
Number of Operations Added by a Subclass

• In order to calculate the number of operations
  added by a subclass, the Software Engineer must
  do the following,
• Obtain the CRC cards for both the parent and
  subclass.
• Pick an operation in the subclass.
• Verify that it is in the parent class.
• If not, increment count.
• Repeat until all operations have been processed.
• Input count into cell

5
Current Class Level

• In order to calculate the current classes level,
  the Software Engineer must consult the
  Inheritance Tree
• In the following Inheritance chart, if we were
  evaluating C2 the level would be 1.
• Please note that the first level, class C, is 0
  not 1.
