C# | Implicitly Typed Arrays Last Updated : 23 Jun, 2021 Comments Improve Suggest changes Like Article Like Report Implicitly typed arrays are those arrays in which the type of the array is deduced from the element specified in the array initializer. The implicitly typed arrays are similar to implicitly typed variable. In general, implicitly typed arrays are used in the query expression.Important points about implicitly typed arrays: In C#, the implicitly typed arrays do not contain any specific data type.In implicitly typed array, when the user initializes the arrays with any data type then compiler automatically convert these arrays into that data type.Implicitly typed arrays generally declared using var keyword, here var does not follow []. For Example: var iarray = new []{1, 2, 3};All types of array-like 1-D, Multidimensional, and Jagged Arrays etc. can be created as an implicitly typed array.In C#, it is necessary to initialize implicitly typed array and have the same data type. Example 1: Below program illustrates how to use 1-Dimensional Implicitly typed array. CSharp // C# program to illustrate // 1-D implicitly typed array using System; public class GFG { // Main method static public void Main() { // Creating and initializing 1-D // implicitly typed array var author_names = new[] {"Shilpa", "Soniya", "Shivi", "Ritika"}; Console.WriteLine("List of Authors is: "); // Display the data of the given array foreach(string data in author_names) { Console.WriteLine(data); } } } Output: List of Authors is: Shilpa Soniya Shivi Ritika Example 2: Below program illustrate the use of Multidimensional implicitly typed arrays. CSharp // C# program to illustrate // 2-D implicitly typed array using System; public class GFG { // Main method static public void Main() { // Creating and initializing // 2-D implicitly typed array var language = new[, ] { {"C", "Java"}, {"Python", "C#"} }; Console.WriteLine("Programming Languages: "); // taking a string string a; // Display the value at index [1, 0] a = language[1, 0]; Console.WriteLine(a); // Display the value at index [0, 2] a = language[0, 1]; Console.WriteLine(a); } } Output: Programming Languages: Python Java Example 3: Below code demonstrate the use of Implicitly typed jagged arrays. CSharp // C# program to illustrate // implicitly typed jagged array using System; class GFG { // Main method static public void Main() { // Creating and initializing // implicitly typed jagged array var jarray = new[] { new[] { 785, 721, 344, 123 }, new[] { 234, 600 }, new[] { 34, 545, 808 }, new[] { 200, 220 } }; Console.WriteLine("Data of jagged array is :"); // Display the data of array for (int a = 0; a < jarray.Length; a++) { for (int b = 0; b < jarray[a].Length; b++) Console.Write(jarray[a][b] + " "); Console.WriteLine(); } } } Output: Data of jagged array is : 785 721 344 123 234 600 34 545 808 200 220 Comment More infoAdvertise with us Next Article C# | Implicitly Typed Arrays ankita_saini Follow Improve Article Tags : C# CSharp-Arrays Similar Reads Implicit Type Casting In programming, data types are the backbone of variable definition and manipulation. Implicit type casting, a fundamental concept in programming languages, involves the automatic conversion of data from one type to another by the compiler.

Syntax: protected abstract bool IsArrayImpl (); Return Value: This method returns true if the Type is an array otherwise, false. Below programs illustrat 3 min read One Dimensional Arrays in C In C, an array is a collection of elements of the same type stored in contiguous memory locations. This organization allows efficient access to elements using their index. Arrays can also be of different types depending upon the direction/dimension they can store the elements.

In an implicitly typed variable, the type of the variable is automatically deduced at compile time by the compiler from the value used to initialize the variable.

The Objective-C array is a single variable array that is used to store different types of elements in the array. Also, we can access the objective-c array using an index.

These data types hold a reference to the data's memory or storage location, unlike value types like integers and booleans.

In simpler terms, a jagged array is an array whose elements are themselves arrays. These inner arrays can have different lengths. Can also be mixed with multidimensional arrays.

These arrays can be manipulated and accessed using pointers, which are variables that store the memory address of another variable.

Arrays can be single-dimensional or multi-dimensional. Â As the name suggests that multi-dimensional means it is a data structure that is used to store similar types of data like(integers, fl 5 min read Like
