Algorithm vs. Code: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on November 6, 2023
An algorithm is a step-by-step procedure for calculations. Code is the actual syntax and instructions written in a programming language implementing an algorithm.

Key Differences

An algorithm is a conceptual sequence of steps that describe how to perform a task. It’s akin to a recipe in a cookbook, detailing the process without being tied to a specific language or technology.
Code is the tangible representation of algorithms, written in a specific programming language. It is the set of instructions that a computer can execute directly, like the actual text of a recipe written in English.
Algorithms are designed to be problem-solving methods, often represented in pseudocode, flowcharts, or plain language. They are language-agnostic and focus on the logic behind solving a particular problem.
In contrast, code is the practical implementation of an algorithm into a form that can be executed by a machine. It includes syntax, programming structures, and the nuances of a programming language.
While an algorithm can be universal and applied in multiple contexts, code is specific and requires a compatible environment to run. An algorithm can exist without code, but code cannot exist without an algorithm or some form of logic it is implementing.
