Parallel Array in C++

In this article I would like to share with you a program that I wrote a long time ago in C++ to demonstrate the concepts of parallel array. According to Wikipedia.org, a group of parallel arrays is a data structure for representing arrays of records. It keeps a separate, homogeneous array for each field of the record, each having the same number of elements. Then, objects located at the same index in each array are implicitly the fields of a single record. Pointers from one object to another are replaced by array indices. This contrasts with the normal approach of storing all fields of each record together in memory.

Thank you and Happy Programming.
