 * @description
 * CWE: 129 Improper Validation of Array Index
 * BadSource: File Read data from file (named c:\data.txt)
 * GoodSource: A hardcoded non-zero, non-min, non-max, even number
 * Sinks: array_read_check_min
 *    GoodSink: Read from array after verifying that data is at least 0 and less than array.length
 *    BadSink : Read from array after verifying that data is at least 0 (but not verifying that data less than array.length)
 * Flow Variant: 22 Control flow: Flow controlled by value of a public static variable. Sink functions are in a separate file from sources.
