# What is direct value (immediate value)? It is a type of constant in programming, and explains the basic concept of using the value as it is at runtime.

## What are Direct Values in Programming?

Direct values, also known as immediate values, are a type of constant used in programming. They refer to values that are used as they are, without any calculations or modifications, at runtime.

In programming, constants are values that do not change throughout the execution of a program. They are typically used to represent fixed values such as numbers, characters, or boolean values. Constants make code more readable and maintainable, as they provide clear indications of the intended meaning behind certain values.

Direct values serve as a specific subset of constants, representing values that are used directly without any further processing. These values are usually embedded directly into the code at the location they are needed, eliminating the need for additional calculations or storage.

For example, consider a piece of code that multiplies two variables, `a` and `b`, and stores the result in another variable, `c`:

“`
c = a * b;
“`

In this case, `a` and `b` are variables that may hold different values at runtime. However, if we want to perform the multiplication with a fixed value, let’s say `2`, we can use a direct value:

“`
c = a * 2;
“`

In this case, `2` is a direct value, as it is used directly in the calculation without any further processing. This provides a more concise and efficient way to express the desired operation.

Direct values are commonly used in programming languages across different paradigms, including procedural, object-oriented, and functional programming. They allow developers to express calculations and operations in a straightforward manner, improving code readability and performance.

It is important to note that direct values are not limited to arithmetic operations. They can also be used in various programming constructs such as conditional statements, loop iterations, and function calls.

In conclusion, direct values, or immediate values, are constants used in programming to represent fixed values that are used directly in calculations or operations at runtime. They enhance code readability and performance by eliminating the need for additional calculations or storage.
