   * @description
   * CWE: 369 Divide by Zero
   * BadSource: connect_socket Read data using a connect socket (client side)
   * GoodSource: A hardcoded non-zero number (two)
   * Sinks:
   *    GoodSink: Check value of or near zero before dividing
   *    BadSink : Divide a constant by data
   * Flow Variant: 84 Data flow: data passed to class constructor and destructor by declaring the class object on the heap and deleting it after use
