Array Definition & Meaning

In programming, a series of objects all of which are the same size and type. Each object in an array is called an array element. For example, you could have an array of integers or an array of characters or an array of anything that has a defined data type. The important characteristics of an array are:

  • Each element has the same data type (although they may have different values).
  • Arrays can have more than one dimension. A one-dimensional array is called a vector ; a two-dimensional array is called a matrix.
