# How to create matrix in c#

### How do you print a matrix?

Example. public class Print2DArray { public static void main(String[] args) { final int[][]

**matrix**= { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } }; for (int i = 0; i <**matrix**. length; i++) { //this equals to the row in our**matrix**. for (int j = 0; j <**matrix**[i].### How do you declare a 2D array?

**Two – dimensional**

**Array**(**2D**–**Array**)**Declaration**– Syntax: data_type[][] array_name = new data_type[x][y]; For example: int[][] arr = new int[10][20];- Initialization – Syntax: array_name[row_index][column_index] = value; For example: arr[0][0] = 1;

### How do you scan a matrix?

How about the following? First ask the user for the number of rows and columns, store that in say, nrows and ncols (i.e. scanf(“%d”, &nrows); ) and then allocate memory for a 2D

**array**of size nrows x ncols. Thus you can have a**matrix**of a size specified by the user, and not fixed at some dimension you’ve hardcoded!### How do you represent a sparse matrix?

**Representing a sparse matrix**by a 2D array leads to wastage of lots of memory as zeroes in the

**matrix**are of no use in most of the cases. So, instead of storing zeroes with non-zero elements, we only store non-zero elements. This means storing non-zero elements with triples- (Row, Column, value).

### What is a matrix in C?

A

**matrix**is a rectangular array of numbers or symbols arranged in rows and columns. The**C**programs in this section perform the operations of Addition, Subtraction and Multiplication on the 2 matrices. The transpose of a**matrix**is the interchange of rows and columns.### What is a matrix simple definition?

A

**matrix**is a collection of numbers arranged into a fixed number of rows and columns. Usually the numbers are real numbers. In general,**matrices**can contain complex numbers but we won’t see those here. Here is an example of a**matrix**with three rows and three columns: The top row is row 1.### How do you use matrix in programming?

**Matrix**entries

1 <= i <= m and 1 <= j <= n, where m is the number of rows and n is the number of columns. **Take** note, because you’ll be **using** them in code. So know how your **programming** language does indices of arrays. If your language starts with the 0-th element, make sure to shift positions by one less.

### What is the two dimensional array?

The

**two**–**dimensional array**can be defined as an**array**of**arrays**. The**2D array**is organized as matrices which can be represented as the collection of rows and columns. However,**2D arrays**are created to implement a relational database lookalike data structure.### What are the types of arrays?

There are three

**different kinds of arrays**: indexed**arrays**, multidimensional**arrays**, and associative**arrays**.### What is 2 dimensional array in C?

A

**two**–**dimensional array in C**can be thought of as a**matrix**with rows and columns. The general syntax used to declare a**two**–**dimensional array**is: A**two**–**dimensional array**is an**array**of several one-**dimensional arrays**. Following is an**array**with five rows, each row has three columns: int my_array[5][3];### What is a one-dimensional array?

A

**one**–**dimensional array**(or single**dimension array**) is a type of linear**array**. Accessing its elements involves a single subscript which can either represent a row or column index. Here, the**array**can store ten elements of type int .### What is Array give example?

**An array**is a group (or collection) of same data types. For

**example an**int

**array**holds the elements of int types while a float

**array**holds the elements of float types.

### What is the difference between 1 D array and 2 D array?

The main

**difference between 1D**and**2D array**is that the**1D array**represents multiple data items as a list while**2D array**represents multiple data items as a table consisting of rows and columns. An**array**allows storing multiple items of the same data type. The elements**in the array**are in subsequent memory locations.### What are the types of arrays in C?

**There are 2**

**types**of**C arrays**.**They are,**

- One dimensional
**array**. - Multi dimensional
**array**. Two dimensional**array**. Three dimensional**array**. four dimensional**array**etc…

### What are two dimensional array explain with example?

A

**2D array**has a type such as int[][] or String[][], with**two**pairs of square brackets. The elements of a**2D array**are arranged in rows and columns, and the new operator for**2D arrays**specifies both the number of rows and the number of columns. For**example**, int[][] A; A = new int[3][4];### What is one dimensional array explain with an example?

An

**array**is**a**collection of**one**or more values of the same type. Each value is called an element of the**array**. The elements of the**array**share the same variable name but each element has its own unique index number (also known as**a**subscript). An**array**can be of any type, For**example**: int , float , char etc.### What is array and its type?

An

**Array**is a Linear data structure which is a collection of data items having similar data**types**stored in contiguous memory locations.**Arrays and its**representation is given below.**Array**Index: The location of an element in an**array**has an index, which identifies the element.**Array**index starts from 0.### What is single and multi dimensional array?

A

**one**–**dimensional array**is a list of variables with the same data type, whereas the**two**–**Dimensional array**is ‘**array**of**arrays**‘ having similar data types. A specific element in an**array**is accessed by a particular index of that**array**.**Arrays**in Java work differently as compared to C++.### How do you declare a 1D and 2D array?

Similar to

**1D array**, a**2D array**can also be**declared**as an int, char, float, double, etc. Here is how we**declare**a**2D array**(here integer**array**):**2D array declaration**datatype arrayVariableName[number of rows] [number of columns] int num[10][5];### What is 3D array?

A

**3D array**is a multi-dimensional**array**(**array**of**arrays**). A**3D array**is a collection of 2D**arrays**. It is specified by using three subscripts:Block size, row size and column size. More dimensions in an**array**means more data can be stored in that**array**.### What is the difference between 2D and multidimensional array?

They all are referred to as a multi-dimension

**array**. The most common**multidimensional array**is a**2D array**.Related Articles.
