In general, array is mutable and linear collection of same data type elements. One common property of all sequential containers is that the elements can be accessed sequentially In computer science, array is a data type that represents a collection of elements (values or variables), each selected by one or more indices (identifying keys) that can be computed at run time during program execution

Such a collection is usually called an array variable or array value
[1] by analogy with the mathematical concepts vector and matrix, array types with one and two indices are.
Also, tuples of ix types are also ix types If we have a vector containing elements (2, 5, 7, 3, 8, 6, 4, 1), and want to create an array slice from the 3rd to the 6th elements, we get (7, 3, 8, 6) Function rank is an important concept to array programming languages in general, by analogy to tensor rank in mathematics Functions that operate on data may be classified by the number of dimensions they act on
Arrays are passed to functions by passing a pointer to the first element Inta[10] [8];// array of 10 elements, each of type 'array of 8 int elements' In c++, sequence containers or sequence collections refer to a group of container class templates in the standard library that implement storage of data elements Being templates, they can be used to store arbitrary elements, such as integers or custom classes
