C# Arrays
An array is a group of contiguous data items that share a common name. Arrays can be of any variable type. In C#, There are three types of Array:
- 1. One-Dimensional Array
- 2. Two-Dimensional Array
- 3. Variable-Size Array
One-Dimensional Array: A list of items can be given one variable name with only one subscript and such a variable is called a One-Dimensional Array. In Mathematics, we often deal with variables that are single subscripted. For instance, we use this equation:
tocalculatee the average of n value of x. The subscripted variable xi refers to the ith element of x. In C#, a single-subscripted variable xi can be expressed as:
x[0], x[1], x[2],....., x[n]
The subscript begins with the number 0 and that is:
x[0] is allowed.
Example:
int[] num=new int[4];
The value of the array elements can be assigned as follows:
num[0]=25;
num[1]=20;
num[2]=30;
num[3]=40;
Two-Dimensional Array: Two-Dimensional Array are stored in memory shown below:
For creating Two-Dimensional Arrays, we must follow the same steps as that of simple arrays, we may create a Two-Dimensional Array-like this:
int[,] num; num=new int[2,4];
or
int[,] num=new int [2,4];
