Question 1

Variables

Answer 1

A variable is very useful. When programming, we often need to store information that it can be used and charged as our program is executed

A variable is a storage location. It is created, and given a name at some point during our program

Question 2

constants

Answer 2

A constant is also a storage location. It contains information that remains the same, throughout the execution of a program.

We could have a constant called ‘Name’, that is assigned the value ‘Sophie’ , but in contrast to a variable, this will not change throughout the program.

Question 3

Data types

Answer 3

There are many data types that can be stored within a variable or a constant,including:string,integars, real numbers, characters and Boolean data.
All data must be identified as a type, so that the computer can read/understand it.

Some programming languages (such as scratch) identify the data type for you, but with others you must specify it manually.
