A variable is a piece of the program that can be changed. Variables can include information added by the user, or answers that are found as a result of a calculation. Conditionals. Conditionals are parts of the program that work if something the program can check to see whether it is true. If that part is not true, then the program won't make it happen. As a programmer, you will frequently want your program to "remember" a value. For example, if your program requests a value from the user, or if it calculates a value, you will want to remember it somewhere so you can use it later. The way your program remembers things is by using variables. For example: As a programmer, you will frequently want your program to "remember" a value.

It is important to remember that there is absolutely no (or at least very little) relationship between the term variable, as it is used in mathematics, and computer program variables. In computer science, a variable is nothing more and nothing less than a named location in memory where data can be stored. In computer programming, any single digit number like 0, 1, 2,....and special characters like $, %, +, -.... etc., are also treated as characters and to assign them in a character type variable, you simply need to put them inside single quotes. In computer programming, variables are used to store information to be referenced and used by programs. They also provide a means of labeling data with a descriptive name. A variable in simple terms is a storage place which has some memory allocated to it.Basically, a variable used to store some form of data. Different types of variables require different amounts of memory, and have some specific set of operations which can be applied on them.

A variable is a way of referring to a storage area in a computer program. This memory location holds values—numbers, text or more complicated types of data like payroll records. This memory location holds values—numbers, text or more complicated types of data like payroll records. Variables in a computer program are analogous to "Buckets" or "Envelopes" where information can be maintained and referenced. On the outside of the bucket is a name. When referring to the bucket, we use the name of the bucket, not the data stored in the bucket.
