With C#, you can create an array of integers, chars, etc. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type stored at contiguous memory locations. This type can be integer, char, float, etc.
The following is an array declaration showing the datatype usage −
datatype[] Name_of_array;
Here,
datatype is used to specify the type of elements in the array.
[ ] specifies the rank of the array. The rank specifies the size of the array.
Name_of_array − specifies the name of the array.
Set the integer array −
int[] a;
Set the double array −
double[] z;
