Tutorial by Topics: array



Arrays allow for the storage and retrieval of an arbitrary quantity of values. They are analogous to vectors in mathematics. Arrays of arrays are analogous to matrices, and act as multidimensional arrays. Arrays can store any data of any type: primitives such as int or reference types such as Object.

An array is a data structure that stores an arbitrary number of values in a single value. An array in PHP is actually an ordered map, where map is a type that associates values to keys.

Array is an ordered, random-access collection type. Arrays are one of the most commonly used data types in an app. We use the Array type to hold elements of a single type, the array's Element type. An array can store any kind of elements---from integers to strings to classes.

Arrays are derived data types, representing an ordered collection of values ("elements") of another type. Most arrays in C have a fixed number of elements of any one type, and its representation stores the elements contiguously in memory without gaps or padding. C allows multidimensional arrays whose elements are other arrays, and also arrays of pointers.

C supports dynamically allocated arrays whose size is determined at run time. C99 and later supports variable length arrays or VLAs.

Arrays are specific data type, representing an ordered collection of elements of another type.

In Go, Arrays can be simple (sometime called "lists") or multi-dimensional (like for example a 2-dimentions arrays is representing a ordered collection of arrays, that contains elements)

N-dimensional arrays or ndarrays are numpy's core object used for storing items of the same data type. They provide an efficient data structure that is superior to ordinary Python's arrays.
