Variables are named storage areas inside computer memory where a program places data during processing. a program sets aside these storage areas by declaring variables, that is, by assigning them a name and indicating what types of data will occupy these areas during processing. You can declare several variables in one statement without having to repeat the data type. in the following statements, the variables i, j, and k are declared as type integer, l and m as long, and x and y as single:. Declaring variables declaring and assigning a variable using a primitive type variables in visual basic are declared using the dim keyword. for example, this declares a new variable called counter with the data type integer:.
