A one-dimensional array is an array where each element in the array points to a specific value of the type specified by the array (all values must be of the same type). For example, we can store integer values in an integer array, character values in a character array and strings in a string array.

Multi-dimensional arrays are implemented as one-dimensional arrays where every element is itself a one-dimensional array, for as many dimensions as required. The overall size of any array (in elements) is the product of all its dimensions, thus a two-dimensional array of 4x5 elements has 20 elements in total, divided into 4 arrays of 5 elements each. However, because all the elements are allocate contiguously, any multi-dimensional array can be treated as if it were one-dimensional. Note that every element of an array must be exactly the same length, even when that element is another array.

The most common type of array we use is a pointer array (an array of pointer elements). Given that a non-null pointer does not store any size information (the number of elements being referred to), we typically use null-terminated pointer arrays, where a null pointer denotes the end of the array being referred to. This makes it possible to implement "jagged" or "irregular" multi-dimensional arrays, where each dimension can be a different length. An array of variable-length strings is an example of a jagged array, such that each element points to a null-terminated character array.

How do you initialise a two dimentional array?

C provides rectangular multidimensional arrays. In C, a two-dimensional array is really a one-dimensional array, each of whose elements is an array. An array is initialized by a list of initializations in braces; each row of a two-dimensional array is initialized by a corresponding sub-list. Example of two dimensional array initialization: char array_example[2][4] = { {11, 12, 13, 14}, {21, 22, 23, 24} };


What does a 2 dimensional array do?

A two dimensional array is a one-dimensional array of one-dimensional arrays. That is, just as we can have an array of integers, we can also have an array of integer arrays. This idea can be extended such that we can have an array of two-dimensional arrays (a three-dimensional array), and so on. We typically use a two-dimensional array to represent a table of rows and columns, where each row is a one-dimensional array.


Could array may have elements that are numbers and strings?

In Java:Not as primitives; but I believe you could create an array of Objects, and then initialize the elemnets as subtypes of the Object class, i.e., any class. I don't think this would be very practical (in Java); if (for example) you need to store information about people's names with their ages, create a class called "Person" that has those two attributes, then create an array of Persons.In Java:Not as primitives; but I believe you could create an array of Objects, and then initialize the elemnets as subtypes of the Object class, i.e., any class.

How do you merge two array without using function?

Take another array big enough to hold both array copy content of these two array into new one. You merged two array and haven't used a single function.!

What is single dimentional?

A single dimension array is an array with one dimension. It is a collection in memory of one or more elements of the same type. int array[100]; declares an array of int's of size 100 elements. The elements are referenced as array[0], the first one, through array[99], the last one.
