What does "value type" mean in programming?
value type is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A type whose variable holds the actual data directly. Assigning a value type copies the data, so changes to one variable do not affect another. Primitives like int and bool are value types. In C# structs are also value types.
Example
"int a = 5; int b = a; b = 10; // a is still 5 — copied by value"
