What are values in programming? According to Techopedia, values are the representation of a qualitative or quantitative data that is held or used in computing or embedded programming. In simple terms, values are the data or information that are held, represented, or used in computers or programming. Values can be of various types, including strings, integers, floats, and Boolean values.
Types of Values
Values can be of various types and forms. Here are some examples of types of values in programming:
- String: A string is a series of characters such as "Hello World!”.
- Integer: An integer is a whole number that can be negative, zero, or positive (ex. -1, 0, 1).
- Float: A float is a number that can have an unlimited number of decimals (ex. 3.14159).
- Boolean: A boolean is a binary value that can be either true or false (ex. true, false).
- Object: An object is a collection of key-value pairs, such as a map, that allow developers to store and access data (ex. {name: "John"}).
How Do Values Work in Programming?
Values are the building blocks of a program. They are used to store and retrieve data, perform calculations, and control the flow of a program. To use values, a language interpreter or compiler must be used to convert the values from text or numbers into something the computer can understand and act on.
In object-oriented programming (OOP), values are referred to as objects. An object is a collection of related data and methods which can be used to access and manipulate the data.
FAQ
What are values in programming?

What is the difference between a string and an integer?
A string is a series of characters such as "Hello World!”, while an integer is a whole number that can be negative, zero, or positive (ex. -1, 0, 1).
What are objects in programming?
Objects are a collection of key-value pairs, such as a map, that allow developers to store and access data (ex. {name: "John"}).
What is object-oriented programming (OOP)?
Object-oriented programming (OOP) is a type of programming language that uses classes and objects, rather than individual instructions, to describe how a program should function. It focuses on objects, or data and the methods related to them, instead of functions and procedures.
