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.

Differentiate single dimensional array to double dimensional array?
A single dimensional array is an array of items. A two-dimensional array is an array of arrays of items.
Explain the Different types of array?
one dementional array and two dementional array
What is an array for 2 times 3?
An array of 2 times 3 is a one-dimensional array of 2 elements each of which is a one-dimensional array of 3 elements. In other words, it is an array of arrays, also known as a two-dimensional array. We can imagine a two dimensional array as being a table with rows and columns. A 2 times 3 array has 2 rows and 3 columns. Each row is itself an array of 3 elements. However, we can also say that each column is an array of 2 elements.
How do you swap rows in 2 dimensional array in Java?
[]temp = array[1] array[2]=array[1] array[1]=[]temp
How will you initialize a 2-d array?
All arrays are one-dimensional. A two-dimensional array is simply a one-dimensional array of one-dimensional arrays: int a[2][3]; This is an array of 2 elements where each element is itself an array of 3 integers. In other words it is an array of 6 integers. The two dimensions simply allow us to split the array into two sub-arrays of 3 elements each.

What is single dimensional array in c plus plus?
A one dimensional array is an array of objects that goes in one "direction". Any array with only one [] is a one dimensional array. For example: int numbers[6]; is a one dimensional array. int numbers[6][3]; is a two dimensional array.Graphical terms:One dimensional array[4]:14 - 75 - 8164 - 234Two dimensional array[2][3]:47 - 178108 - 8517 - 128It didn't come out quite how I wanted it...
In mathematics what is an array?
An array is a 2-dimensional rectangle with length and width. An array also has area and perimeter.

What is meant by irregular dimensional array?
An irregular dimensional array is a special type of multi-dimensional array.First we must understand that a multi-dimensional array is just an array of arrays. Each element in the array is, itself, an array of elements.A regular multi-dimensional array will be an array of size n, with each element containing a separate array of size m. That is, each sub-array has the same size.An irregular multi-dimensional array will be a multi-dimensional array in which each sub-array does not contain the same number of elements.Regular array:array[0] = new array{0, 1, 2}array[1] = new array{3, 4, 5}array[2] = new array{6, 7, 8}array[3] = new array{9, 10, 11}This regular array is an array of size 4 in which each sub-array is of size 3.Irregular array:array[0] = new array{0, 1, 2}array[1] = new array{3, 4}array[2] = new array{5, 6, 7}array[3] = new array{8, 9, 10, 11}This irregular array is an array of size 4 in which the size of each sub-array is not the same.
How does two dimensional array differ from single dimensional array?
A one dimensional array is a scalar value repeated one or more times.A two dimensional array is an array of one dimensional arrays.A three dimensional array is an array of two dimensional arrays, and so forth.The one dimensional array is like a list of things, where the two dimensional array is like an array of things. (Think one row of a spreadsheet versus the whole spreadsheet.)[addendum]Every level of array depth is also a level of pointer depth. For example: A 3 dimensional int array is an int***. So a one dimensional int array is an int*, and a two dimensional int array is an int**. This is only important if you are doing pointer work, but it can become very important.
What is a multi array?
A two-dimensional array is the simplest multi-dimensional array and is implemented as a one-dimensional array where every element is itself a one-dimensional array. We can imagine a two-dimensional array as being a table of rows and columns where every row is an array in its own right. A three-dimensional array is simply a one-dimensional array of two-dimensional arrays, which can be imagined as being an array of tables. Extending the concept, a four-dimensional array is a table of tables. Multi-dimensional arrays may be jagged. That is, a two-dimensional array may have rows of unequal length. Unlike regular arrays, jagged arrays cannot be allocated in contiguous memory. Instead, we use the outer array (the first dimension) to store pointers to the inner arrays. An array of strings (character arrays) is an example of a two-dimensional jagged array.
Give an example of a multi dimensional array in Cpp?
// 2 dimensional array (a sudoku puzzle): char sudoku[9][9]; // 3 dimensional array (100 sudoku puzzles): char sudokus[100][9][9]
What does the word array mean in math?
An array is a set of numbers that form some sort of regular arrangement. A linear array is a 1-dimensional array consisting of a row or a column of a set of numbers. A 2-dimensional array is a rectangular arrangement of numbers. And there are arrays with higher dimensions. The elements of an array need not be numbers: they could be variables, functions or expressions. In other words, it's a picture to describe a multiplication problem.
