7.2. What are Values?
Overview
Medium Summary
In programming, values are the actual data stored in variables and constants, such as integers or strings. Understanding values is fundamental to manipulating data correctly within a program.

Detailed Explanation
In programming, 'values' refer to the actual pieces of data that a program works with. These are the real, tangible elements that a program can manipulate, store, or use in computations. Values might take many forms depending on the type of data they represent. For example, a number like 10 is a numeric value, while the text 'Hello' is a string value. The distinction between values and their storage mechanisms (like variables) is crucial in programming.
Examples & Analogies
Think of values as the ingredients in a recipe. Just as you need specific ingredients to create a dish, programs need specific values to perform operations and calculations.

Detailed Explanation
Values in programming can be categorized into different types based on what they represent. Common examples include integers (like 10, which is a whole number), strings (like 'Hello', which represent text), and boolean values (true/false, which represent logical states). Each of these examples illustrates the variety of data types that can be considered as values in a program.
Examples & Analogies
Consider a digital library. The integer 10 could represent the number of books, 'Hello' could be the title of a book, and ‘true/false’ could indicate whether a book is available for checkout.
