A flowchart has long been a useful tool for businesses and other professional fields. In addition to assisting in planning or training activities with different types of knowledge, it also helps you logically make certain decisions.

There are many popular types of flowcharts, and program flowchart is among them. This article will give you the essential information about the program flowchart. Read on for more! 

What Is Program Flowchart?

A flowchart is a type of professional diagram that is frequently applied to illustrate the steps in a process. Programming flow chart is one of many types of flowcharts. It transforms a complex process into a simple and understandable flow of method using rhombus, circle, and parallelogram images.

Moreover, a programming flow chart not only represents a data flow while writing a program or algorithm but also analyzes the logic behind the program to process the code.

Utilizing this simple flow chart will help you determine how to solve the work with a program, plan, or any grand-scheme project. As a result, your efficiency and productivity will increase greatly.

Program Flowchart: Pros And Cons

To better understand the actual programming flow chart, let's look at the disadvantages and advantages of the flow chart below:


  • Suitable when you need to understand programming or a logical structure.
  • Help programmers control loopholes in the program creation process
  • Simplify the modification process
  • Assist designers when they are reviewing programs
  • Save time for developing a new simple program or application.


  • Designers may find it difficult to draw complex programs when using these programming diagrams.
  • Individuals may find it difficult to work if there is no agreement on common standards.
  • Existing diagrams or programming applications are difficult to duplicate
  • Engineers face a challenge when changing a flow chart based on changes to an application or a website.

Flowchart Symbols

Similar to other common types of diagrams, programming flow chart also uses the following standard flowchart symbols:

  • Flowline: This common symbol functions as a link between two blocks. This line shows the process direction and relationships between the various steps or elements.
  • Input/ Output: This basic flow chart symbol represents the process of importing or exporting external data. The system reads the inputs and generates a result. Parallelograms are used as input and output symbols.
  • Terminal: It represents the beginning or end of the flow chart. This icon usually has the text "Start" or "End".
  • Processing: In between the input and output, there is the processing section, whic is depicted using rectangular shapes
  • Decision: This diamond icon is used to determine whether the outcome is correct or incorrect when making a series of decisions.
  • On-page connector: connects multiple flows on the same page.
  • Off-page connector: links different flows that appear on different pages.
  • Document: The printout or report is denoted by this symbol.
  • Predefined process/ function: indicates a process or workflow that requires predefined work.
  • Preparation: The preparation notation is used to differentiate between the steps involved in preparing the work and the steps involved in completing it.

How To Make Program Flowchart

There are many flowchart tools available; you can create yours with the few simple steps below. Read on as we provide you with step-by-step instructions on how to construct this type of diagram: 

Step 1: Determine the purpose of the programming flowchart

Of course, the first and most crucial step is to determine why you need a flow chart. In this step, you should also clearly define the scope of the flowchart to avoid redundant content. Identifying the right goal will make it easier to draw and avoid going in the wrong direction. 

Step 2: Choose appropriate symbols

After you've defined your goal, you'll need to figure out which symbol type to use. We suggest you take a closer look at the meaning of the various types of standard options we discussed earlier in order to create powerful visuals.

Step 3: Plan the shapes

There are a wide variety of shapes, but you must select the right type to create a flow of logic. Consequently, your diagram will look more concise and effective. 

Step 4: Place the shapes and symbols

The next step in making flow diagrams is organizing the program and applying symbols. Then, you use the lines with arrows to connect the standard shapes. Make sure that you arrange the contents in the appropriate sequence of instructions in this step.

Step 5: Check the structure 

After completing the scheme, you must carefully review it to see if any steps were skipped or have a mistake. 

Overall, you can make a flow chart with Google Docs, Google Sheets or use a diagramming tool or flowchart freeware that integrates many modern features out there. With this flowcharting software, you can even create an advanced flow chart.

Rules For Making Program Flowchart

To build a logic flow chart, you need to adhere to the following principles and tips:

  • Must have a START and END on each flowchart.
  • Control flow to ensure that it is from top to bottom or left to right.
  • Use connector notation if the flowchart is long and complex.
  • Avoid flow intersection
  • Presented in a clear and easy-to-understand manner.
