1. Complex Conditional: a complex conditional statement
2. Complex Method: a method with high cyclomatic complexity
3. Duplicate Code: a code clone within a method
4. Empty Catch Block: a catch block of an exception is empty
5. Long Identifier: an identifier with excessive length
6. Long Method: a method is excessively long
7. Long Parameter List: a method has long parameter list
8. Long Statement: an excessive long statement
9. Magic Number: an unexplained number is used in an
   expression
10. Missing Default: a switch statement does not contain a
    default case
11. Virtual Method Call from Constructor: a constructor calls a
    virtual method.

Cyclomatic complexity:

It is a measure of number of linearly independent paths in it. It is a software metric used to indicate the complexity of a program. A control flow graph can used to determine it with a formula.

==cyclomatic complexity = E-N+2P ==

E = number of edges in the flow graph.
N = number of nodes in the flow graph.
P = number of nodes that have exit points
