Frequently Asked Questions About KS3 Data Types
What is a data type?
A data type is a classification of the type of value that a variable or expression can hold in a programming language.
What are the basic data types in most programming languages?
The basic data types in most programming languages are integers, floating-point numbers, characters, and strings. Some languages also include Boolean as a basic data type.
What is the difference between a primitive data type and a non-primitive data type?
Primitive data types are the basic data types that are built into a programming language, such as integers and floating-point numbers. Non-primitive data types, also known as reference data types, are more complex and are defined by the programmer or provided by the language or libraries. Examples of non-primitive data types include arrays and objects.
What is a null value?
A null value is a special value that represents the absence of a value or a default value. It is often used to indicate that a variable has been declared but has not been assigned a value yet.
What is a variable?
A variable is a named storage location in memory that can hold a value of a certain data type. The value stored in a variable can be changed during the execution of a program. Variables are used to store data that can be manipulated by the program.
