Flow charts and algorithm are tools used by software developers when creating new programs. In this article we see the content of both titles so that you understand all their differences. We will see aspects related to its complexity, geometric diagrams and scope of use, use, users, debugging, solutions, branches and loops.
What is a flowchart?
It is a diagram that graphically represents the steps a program takes to process data. They use different geometric shapes to describe the different actions that the program performs. For example, a parallelogram can be used to indicate input and output; a diamond can indicate a logical decision, while a rectangular box can be used to indicate a simple mathematical operation.
In many cases, a programmer draws a flowchart with pencil and paper or by connecting shapes on a computer screen with software. In a large system, flow charts act as an important document for both the system and individual programs, this is because it accurately summarizes the functions of a program in easy to understand symbols clearly explained in English.
In any case, the program has problems, it saves time on the part of the programmer, since he will have to review the flowchart in a few minutes before examining the program.
What is an algorithm?
It is a well-defined step-by-step process used in data processing (providing a solution to a particular problem). An algorithm precisely defines the steps a program takes to perform an operation. Includes input and output and logical comparisons. When an algorithm is used on a computer, different operations, such as addition and subtraction, are combined to perform more complicated mathematical operations.
Algorithms are commonly written in natural language or plain English. Algorithms can also be presented using pseudocode, flowcharts, drakon diagrams, among others.
Difference Between Algorithm and Flowchart
Flowchart | Algorithm | |
Description | A flowchart is a diagram that represents different steps that can help solve a problem. It is a diagram that is done step by step using different shapes and sizes of arrows that show their connection. | An algorithm is a step-by-step process used to solve mathematical or sometimes computational problems. It can be expressed in any language, including natural language, pseudocode, and programming language. |
Complexity | Easy to create and be understood by anyone. | It is relatively difficult to understand by a layman. |
geometric diagrams | It uses various types of geometric diagrams, charts, and symbols that are interlinked with arrows or lines. | The algorithm does not incorporate any type of geometric figure. |
scope of use | The flowchart can be used in various fields to represent a process. | The algorithm is basically employed in the field of computer science and mathematics only. |
Use | It is used to analyze, design, document or manage a program in various fields. | It can be used to define the notion of decidability. |
Users | The user of a flowchart does not require knowledge of a programming language to write and understand a flowchart. | The user needs knowledge of a programming language to write and understand an algorithm. |
Depuration | Easier to debug errors. | Difficult to debug errors. |
Implementation | Rules are not used. | Predefined rules are made. |
branch and loop | Simple to show branches and loops. | Complex of showing branches and loops. |
Solution | The solution is displayed in graphical format. | The solution is shown in non-computer language. |
