What is array?
An array is a collection of values of the same data type. The variables in an array are called the array elements. Array elements are accessed using a single name and an index number representing the position of the element within the array. Array is a reference type data type.
The following figure shows the array structure in the system’s memory:
An array needs to be declared before it can be used in a program. You can declare an array by using the following statement: Source code | | int[] Score; int[] Score; |
How to declare an array in c# with example step by step tutorial
The following is an example of the array declaration:
The explanation of the elements of the preceding statement is as follows: datatype[] Arrayname; | * datatype: Is used to specify the data type for the elements, which will be stored in the array. * [ ]: Is used to specify the rank of the array. Rank is used to specify the size of the array. * Arrayname: Is used to specify the name of the array using which the elements of the array will be initialized and manipulated.
Initializing Array:-
Array is a reference type, therefore you need to use the new keyword to create an instance of the array. The following statement is an example of array initialization:
The preceding two statements can be combined into a single statement, and written, as follows: Source code | | int[] Score = new int[10];
In C#, the array subscript always starts with zero.
Assigning values to the array:-
You can assign values to each
