    What is a Flowchart and its Types?


    Flowcharts are graphical representations of data, algorithms, or processes, providing a visual approach to understanding code.

    • Flowcharts illustrate step-by-step solutions to problems, making them useful for beginner programmers.

    • Flowcharts help in debugging and troubleshooting issues.

    • Flowchart consists of sequentially arranged boxes that depict the process flow.

    Since it visually represents an algorithm or workflow, it is easier to interpret and understand. However, to create an effective Flowchart, certain standardised rules must be followed, ensuring clarity and consistency across different professionals worldwide.

    Flowchart Symbols

    Different types of boxes are used to make Flowchart Symbols. All the different kinds of boxes are connected by arrow lines. Arrow lines are used to display the flow of control. Let's learn about each box in detail.

    Uses of Flowcharts in Computer Programming/Algorithms

    The following are the uses of a Flowchart:

    • It is a pictorial representation of an algorithm that increases the readability of the program.

    • Complex programs can be drawn in a simple way using a Flowchart.

    • It helps team members get an insight into the process and use this knowledge to collect data, detect problems, develop software, etc.

    • A Flowchart is a basic step for designing a new process or adding extra features.

    • Communication with other people becomes easy by drawing Flowcharts and sharing them.

    When to Use Flowchart?

    Flowcharts are mainly used in the below scenarios:

    • It is most importantly used when programmers make projects. As a Flowchart is a basic step to make the design of projects pictorially, it is preferred by many.

    • When the Flowcharts of a process are drawn, the programmer understands the non-useful parts of the process. So, Flowcharts are used to separate sound logic from the unwanted parts.

    • Since the rules and procedures of drawing a Flowchart are universal, a Flowchart serves as a communication channel to the people who are working on the same project for better understanding.

    • Optimizing a process becomes easier with Flowcharts. The efficiency of the code is improved with the Flowchart drawing.

    Types of Flowcharts

    Three types of Flowcharts are listed below:

    1. Process Flowchart: This type of Flowchart shows all the activities that are involved in making a product. It provides a pathway to analyze the product to be built. It is most commonly used in process engineering to illustrate the relation between the major as well as minor components present in the product. It is used in business product modelling to help understand employees about the project requirements and gain some insight into the project.

    1. Data Flowchart: It is used to analyze the data, specifically it helps in analyzing the structural details related to the project. Using this Flowchart, one can easily understand the data inflow and outflow from the system. It is most commonly used to manage data or to analyze information to and fro from the system.

    1. Business Process Modelling Diagram: Using this Flowchart or diagram, one can analytically represent the business process and help simplify the concepts needed to understand business activities and the flow of information. This Flowchart illustrates the business process and models graphically which paves the way for process improvement.

    Types of boxes used to make a Flowchart

    There are different types of boxes that are used to make Flowcharts. All the different kinds of boxes are connected to one another by arrow lines. Arrow lines are used to display the flow of control. Let's learn about each box in detail.

    1. Terminal


    This box is of an oval shape which is used to indicate the start or end of the program. Every Flowchart diagram has an oval shape that depicts the start of an algorithm and another oval shape that depicts the end of an algorithm. For example:


    2. Data


    This is a parallelogram-shaped box inside which the inputs or outputs are written. This basically depicts the information that is entering the system or algorithm and the information that is leaving the system or algorithm. For example: if the user wants to input a from the user and display it, the Flowchart for this would be:


    3. Process


    This is a rectangular box inside which a programmer writes the main course of action of the algorithm or the main logic of the program. This is the crux of the Flowchart as the main processing codes is written inside this box. For example: if the programmer wants to add 1 to the input given by the user, he/she would make the following Flowchart:


    4. Decision


    This is a rhombus-shaped box, control statements like if, condition like a > 0, etc are written inside this box. There are 2 paths from this one which is "yes" and the other one is "no". Every decision has either yes or no as an option, similarly, this box has these as options. For example: if the user wants to add 1 to an even number and subtract 1 if the number is odd, the Flowchart would be:


    5. Flow


    This arrow line represents the flow of the algorithm or process. It represents the direction of the process flow. in all the previous examples, we included arrows in every step to display the flow of the program. arrow increases the readability of the program.

    6. On-Page Reference


    This circular figure is used to depict that the Flowchart is in continuation with the further steps. This figure comes into use when the space is less and the Flowchart is long. Any numerical symbol is present inside this circle and that same numerical symbol will be depicted before the continuation to make the user understand the continuation. Below is a simple example depicting the use of On-Page Reference


    Advantages of Flowchart

    • It is the most efficient way of communicating the logic of the system.

    • It acts as a guide for a blueprint during the program design.

    • It also helps in the debugging process.

    • Using Flowcharts we can easily analyze the programs.

    • Flowcharts are good for documentation.

    Disadvantages of Flowchart

    • Flowcharts are challenging to draw for large and complex programs.

    • It does not contain the proper amount of details.

    • Flowcharts are very difficult to reproduce.

    • Flowcharts are very difficult to modify.
