For each type T and each non-negative integer constant n, there is an array type denoted [n]T; arrays of differing lengths are thus of different types. Dynamic arrays are available as "slices", denoted []T for some type T. These have a length and a capacity specifying when new memory needs to be allocated to expand the array. Several slices may ...
Elements can be removed from the end of a dynamic array in constant time, as no resizing is required. The number of elements used by the dynamic array contents is its logical size or size, while the size of the underlying array is called the dynamic array's capacity or physical size, which is the maximum possible size without relocating data.

In addition to support for vectorized arithmetic and relational operations, these languages also vectorize common mathematical functions such as sine. For example, if x is an array, then y = sin (x) will result in an array y whose elements are sine of the corresponding elements of the array x. Vectorized index operations are also supported.
Class-based object-oriented programming languages support objects defined by their class. Class definitions include member data. Message passing is a key concept, if not the main concept, in object-oriented languages. Polymorphic functions parameterized by the class of some of their arguments are typically called methods.
array + 1 means 0x1004: the "+ 1" means to add the size of 1 int, which is 4 bytes; *array means to dereference the contents of array. Considering the contents as a memory address (0x1000), look up the value at that location (0x0002); array[i] means element number i, 0-based, of array which is translated into *(array + i).
Delphi defines an array of const data type that may be associated with the last formal parameter. Within the routine definition the array of const is an array of TVarRec, an array of variant records. [11] The VType member of the aforementioned record data type allows inspection of the argument’s data type and subsequent appropriate handling.
