Keep it personal, relevant and interactive and they'll come back for more. Keep it open. Your site needs to be ready and able to connect to outside services.An array is a set of values, which are termed elementsthat are logically related to each other. For example, an array may consist of the number of students in each grade in a grammar school; each element of the array is the number of students in a single grade. Similarly, an array may consist of a student's grades for a class; each element of the array is a single grade.

It is possible individual variables to store each of our data items. For example, if our application analyzes student grades, we can use a separate variable for each student's grade, such as englishGrade1englishGrade2etc. This approach has three major limitations:. The indexes of an array range from 0 to one less than the total number of elements in the array. When you use Visual Basic syntax to define the size of an array, you specify its highest index, not the total number of elements in the array.

You can work with the array as a unit, and the ability to iterate its elements frees you from needing to know exactly how many elements it contains at design time. Let's create an array named students to store the number of students in each grade in a grammar school. The indexes of the elements range from 0 through 6. Using this array is simpler than declaring seven variables. The students array in the preceding example is a one-dimensional array because it uses one index.

An array that uses more than one index or subscript is called multidimensional. For more information, see the rest of this article and Array Dimensions in Visual Basic.

If you have an existing array, you can redefine its size by using the ReDim statement. You can specify that the ReDim statement keep the values that are in the array, or you can specify that it create an empty array. The following example shows different uses of the ReDim statement to modify the size of an existing array. For more information, see the ReDim Statement. You can access each location in an array by using an index of type Integer.

You can store and retrieve values in an array by referencing each array location by using its index enclosed in parentheses. Indexes for multidimensional arrays are separated by commas. You need one index for each array dimension. By using an array literal, you can populate an array with an initial set of values at the same time that you create it. When you create an array by using an array literal, you can either supply the array type or use type inference to determine the array type.Create a variable Insert a variable value in a text Create an array.
