What is variable?
Throughout computer programming, a variable is indeed a named container for a specific set of bits or type of data. A variable is indeed an abstract storage location with an associated symbolic name that holds some unidentified quantity of information made reference to as a value. Eventually, a memory address may be used to link or identify a variable. In addition to using the variable name or the variable itself, depending on circumstances, the stored value is typically referenced by the variable name. The name can be used independently of the precise information it represents thanks to the separation of name as well as content. During run time, a value can be bound to an identification number in computer source code.
