variable

In programming, a variable is a value that can change, depending on conditions or on information passed to the program. Typically, a program consists of instruction s that tell the computer what to do and data that the program uses when it is running. The data consists of constants or fixed values that never change and variable values (which are usually initialized to "0" or some default value because the actual values will be supplied by a program's user). Usually, both constants and variables are defined as certain data type s. Each data type prescribes and limits the form of the data. Examples of data types include: an integer expressed as a decimal number, or a string of text characters, usually limited in length.

In object-oriented programming , each object contains the data variables of the class it is an instance of. The object's method s are designed to handle the actual values that are supplied to the object when the object is being used.

The context was clear enough. I understood it very well.

This blends mathematical world with programming world.

It's not clear enough. I am actually just learning how to draw a flow chart and I know variable is a storage location that holds alphabets and alphanumeric, but in a case where you are drawing a flow chart adding two numbers, you've drawn your start, then you want to declare your variable what do you write or declare is it sum, A, B or what else could it be.

A variable is not a value in programming.
In programming, a variable is a container that can hold some value.
