   * CWE: 129 Improper Validation of Array Index
   * BadSource: fscanf Read data from the console using fscanf()
   * GoodSource: Larger than zero but less than 10
   * Sinks: char
   *    GoodSink: Ensure the array index is valid
   *    BadSink : Improperly check the array index by not checking the upper bound
   * Flow Variant: 07 Control flow: if(static_five==5) and if(static_five!=5)
