   * CWE: 187 Partial Comparison
   * BadSource: fromConsole Read input from the console
   * GoodSource: Provide a matching password
   * Sinks: str
   *    GoodSink: Compare the 2 passwords correctly
   *    BadSink : use wcsstr() to do password match, which is a partial comparison
   * Flow Variant: 07 Control flow: if(static_five==5) and if(static_five!=5)
