A programming flowchart is a diagram that illustrates the logical steps involved in a software program or programming task. It can be used to help you plan, design, and debug your code.

Flowcharts use a set of standard symbols to represent different types of actions, such as input, output, processing, and decision making. The following are the most common flowchart symbols:

  • Terminal: This symbol represents the beginning or end of the flowchart.
  • Input/Output: This symbol represents an input or output operation.
  • Processing: This symbol represents a calculation or other processing operation.
  • Decision: This symbol represents a decision point.
  • Connector: This symbol is used to connect different parts of the flowchart.

There are other symbols used to show more functionalities. 

  • One page connector: used for join different flowline
  • Off-page connector: used to connect the flowchart portion on different page. 
  • Predefined process/function: represents a group of statements performing one processing task

To create a programming flowchart, you can use a flowcharting software tool or simply draw it by hand. Here are the steps involved in creating a flowchart:

  1. Identify the steps involved in your program or programming task.
  2. Assign a symbol to each step.
  3. Connect the symbols with arrows to show the flow of logic.
  4. Label the arrows with the conditions that determine the next step.
  5. Annotate the flowchart with comments to explain the steps in more detail.

Here is an example of a flowchart that calculates the factorial of a number:

Start
Input a number
Set factorial to 1
For each number from 1 to the input number
    Increase factorial by number
End For
Output factorial
Stop

This flowchart uses the following symbols:

  • Terminal: The start and end of the flowchart are represented by ovals.
  • Input/Output: The input and output operations are represented by rectangles.
  • Processing: The calculation of the factorial is represented by a diamond.
  • Connector: The connector is used to connect the beginning and end of the loop.

Let’s create one flowchart. 

using System;

class Program
{
 static void Main()
 {
 int a, b;

 // Start of the program
 
 // Declare variables a and b
 Console.WriteLine("Comparison of Two Numbers");

 // Read values of a and b from the user
 Console.Write("Enter the value of a: ");
 a = Convert.ToInt32(Console.ReadLine());
 Console.Write("Enter the value of b: ");
 b = Convert.ToInt32(Console.ReadLine());

 // Check if a is greater than b
 if (a > b)
 {
 // Exit point when a is bigger
 Console.WriteLine("a is bigger");
 }
 else if (a < b)
 {
 // Exit point when a is smaller
 Console.WriteLine("a is smaller");
 }

 // End of the program
 }
}

Let’s look at the C# code for flowchart.

Flowcharts can be a helpful tool for planning, designing, and debugging your code. They can also help you communicate your ideas to other programmers. If you are new to programming, I encourage you to learn how to create flowcharts. They can be a valuable asset in your programming toolkit.

Here are some additional tips for creating programming flowcharts:

  • Use clear and concise symbols.
  • Label the arrows with the conditions that determine the next step.
  • Annotate the flowchart with comments to explain the steps in more detail.
  • Use a consistent style throughout the flowchart.
  • Make sure the flowchart is easy to read and understand.

There are many different flowcharting software tools available. Some popular options include Lucidchart, Microsoft Visio, and SmartDraw. These tools can help you create professional-looking flowcharts quickly and easily.

I hope this has helped you learn how to create a programming flowchart.
