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.
In this example, a variable 'x' is declared which has a type array of int, that is, int[]. The variable x is initialized to reference a newly created array object. The expression 'int[] = new int[50]' specifies that the array should have 50 components. To know the length of the Array, we use field length, as shown.
