Difference between Algorithm and Flowchart : Their Roles in Problem Solving

The world of computer science and problem solving relies heavily on algorithms and flowcharts. These two concepts play a crucial role in breaking down complex problems into manageable steps. In this article, I will explain fundamental difference between algorithm and flowchart, their purposes, characteristics, uses of Algorithm and Flowchart in various domains and how they relate to each other. By understanding these concepts, you will gain valuable insights into the foundations of problem-solving in computer science.

What is an Algorithm?

algorithm (2)An algorithm can be defined as a step-by-step set of instructions designed to solve a specific problem. It serves as a roadmap for solving problems efficiently and effectively. Algorithms are essential in computer science and problem-solving as they provide a structured approach to finding solutions. They have several key characteristics, including being unambiguous, finite, and producing a clear output for a given input. We will delve deeper into these characteristics to understand the essence of algorithms.

Purpose of Algorithm in Computer Science and Problem Solving 

Algorithms serve various purposes in computer science and problem-solving. They are the building blocks of computational thinking, enabling programmers to devise efficient solutions. They provide a systematic approach to problem-solving, allowing programmers to analyze, design, implement, and evaluate their solutions. By understanding the purpose of algorithms, we can appreciate their significance in various domains, such as sorting, searching, optimization, and data analysis.

Characteristics of Algorithm

Algorithms possess specific characteristics that differentiate them from other problem-solving techniques. We will explore these characteristics in detail, including their precision, determinism, effectiveness, and efficiency. Understanding these characteristics will help you create well-designed and reliable algorithms.

Components of Algorithm

Being aware of these limitations will enable you to use flowcharts effectively while considering alternative approaches when necessary.

Difference between Algorithm and Flowchart

Algorithm Flowchart
An algorithm is a conceptual representation of a solution to a problem. A flowchart is a visual representation of an algorithm.
Algorithm consists of a sequence of steps or instructions that outline the logic of solving the problem. Flowchart uses various symbols and arrows to depict the flow of control and decision-making steps involved in the algorithm.
Algorithms are more abstract and focus on the logical and mathematical aspects of problem-solving. Flowcharts provide a more detailed and visual representation of an algorithm.
Algorithm describes the high-level steps required to solve a problem without specifying the exact implementation details. Flowchart breaks down the steps into individual actions, decisions, and conditions, making it easier to understand the exact flow and logic of the algorithm.
Algorithms are typically represented using natural language, pseudocode, or programming languages. Flowcharts are represented graphically using various symbols and arrows.
Algorithm can be written in a textual format, making them more suitable for implementation in programming languages. Flowcharts provide a visual representation of the algorithm’s flow and logic, making it easier to understand and communicate the steps involved.
The primary purpose of an algorithm is to provide a logical and systematic approach to problem-solving. Flowcharts serve the purpose of visualizing and communicating the algorithm.
Algorithm focuses on defining the steps required to solve a problem efficiently and effectively. Flowchart provide a graphical representation that aids in understanding the logical flow, decision-making, and control structures involved in the algorithm.
Algorithm allows programmers to choose the most suitable programming constructs and language-specific optimizations. Flowchart serves as a tool for understanding and communicating the algorithm’s flow rather than being directly executable.



Algorithms and flowcharts are essential tools in problem-solving and computer science. Understanding their differences, purposes, and characteristics will empower you to approach problem-solving with a systematic and structured mindset. By leveraging algorithms and flowcharts effectively, you can tackle complex problems more efficiently and enhance your programming skills.
