A typical declaration for an array in C++ is: type name [elements]; where type is a valid type (such as int, float...), name is a valid identifier and the elements field (which is always enclosed in square brackets []), specifies the length of the array in terms of the number of elements.
The declaration consists of two parts. The type of the array and the array name. The type of an array has a data type that determines the types of the elements within an array (int, String, float in our case) and a pair of square brackets [] . The brackets indicate that we have an array. Collections serve the similar purpose.
