What is array in C# with example?

Arrays are used to store multiple values in a single variable, instead of declaring separate variables for each value. To declare an array, define the variable type with square brackets: string[] cars; We have now declared a variable that holds an array of strings.

How do you display an array in C#?

C# Passing Array to Function Example: print array elements

  1. using System;
  2. public class ArrayExample.
  3. {
  4. static void printArray(int[] arr)
  5. {
  6. Console.WriteLine(“Printing array elements:”);
  7. for (int i = 0; i < arr.Length; i++)
  8. {

What are the types of array in C#?

In C#, an array can be of three types: single-dimensional, multidimensional, and jagged array.

What is the default value of string array in C#?

The array indexes start at zero. The default value of numeric array elements are set to zero, and reference elements are set to null .

How do you write an array?

You can make an array of int s, double s, or any other type, but all the values in an array must have the same type. To create an array, you have to declare a variable with an array type and then create the array itself. Array types look like other Java types, except they are followed by square brackets ( [] ).

What is array in .NET framework?

NET Common Language Runtime (CLR) supports single-dimensional arrays, multidimensional arrays, and jagged arrays (arrays of arrays). All array types are implicitly derived from System. Array, which itself is derived from System. Object.

How do you return an array from a function in C#?

Solution 1

  1. string x = “XXX”; string y = x; x = “YYY”; Console. WriteLine(“{0}:{1}”, x, y);
  2. if (strArr == strArr2) Console.
  3. string[] ret = { “Matthew”, “Mark”, “Luke”, “John” };
  4. static string[] ret = { “Matthew”, “Mark”, “Luke”, “John” }; static string[] GetNames() { return ret; } Now, you will get.

What is jagged array in C# with example?

A jagged array is an array whose elements are arrays, possibly of different sizes. A jagged array is sometimes called an “array of arrays.” The following examples show how to declare, initialize, and access jagged arrays. jaggedArray[0] = new int[5]; jaggedArray[1] = new int[4]; jaggedArray[2] = new int[2];

How do you use arrays?

What is multidimensional array in C#?

The multidimensional array is also known as rectangular arrays in C#. It can be two dimensional or three dimensional. The data is stored in tabular form (row * column) which is also known as matrix. To create multidimensional array, we need to use comma inside the square brackets.

    • How to initialize array of structure in C?

    Structure Initialization Just after structure declaration put the braces (i.e. {}) and inside it an equal sign (=) followed by the values must be in the order of members specified also each value must be separated by commas. The example below will show how to initialize structure variable in C programming.

    How to get the value from the array in C?

    Parameters. A 32-bit integer that represents the first-dimension index of the Array element to get. A 32-bit integer that represents the second-dimension index of the Array element to get.

  • Returns. The value at the specified position in the two-dimensional Array.
  • Exceptions. The current Array does not have exactly two dimensions.

    • How to create an array from user input in C?

    Input and Output Array Elements. Here’s how you can take input from the user and store it in an array element. // take input and store it in the 3rd element scanf(“%d”, &mark[2]); // take input and store it in the ith element scanf(“%d”, &mark[i-1]); Here’s how you can print an individual element of an array.
