data structures are classes that are used to organize data and provide various operations upon their data.

Most common and well-known data structure is the array, which contains a contiguous collection of data items that can be accessed by an ordinal index.

Structural testing is white box testing, not black box testing, since black boxes are considered opaque and do not permit visibility into the code.

Structural testing is a way to test software with knowledge of the internal workings of the code being tested
