Difference between Flowchart and Algorithm

Difference between Flowchart and Algorithm

Difference between flowchart and algorithm is the same as the difference between a movie and its story, or the difference between a fiction novel and the story, or the difference between a comics or the story.

Algorithms and flowcharts are two different tools used for creating new programs, especially in computer programming. An algorithm is a step-by-step analysis of the process, while a flowchart explains the steps of a program in a graphical way.

Definition of Flowchart

A flowchart is a pictorial or graphical representation of a process. Each step in the process is represented by a different symbol and contains a short description of the process step. The flow chart symbols are linked together with arrows showing the process flow direction. This pictorial representation can give a step-by-step solution to the given problem.

  • Easy to draw.
  • Easy to understand the logic.
  • Easy to identify mistakes by the non-computer person.
  • Easy to show branching and looping.


  • Time-consuming.
  • Difficult to modify.
  • Very difficult to draw a flowchart for big or complex problems.

Example: Print 1 to 20

Definition of Algorithm

An Algorithm is a finite sequence of well-defined steps for solving a problem in a systematic manner. It is written in natural languages like English.

  • Easy to write.
  • Human readable techniques to understand the logic.
  • Algorithms for big problems can be written with moderate efforts.


  • Difficult to debug.
  • Difficult to show branching and looping.
  • Jumping (goto) makes it hard to trace some problems.

Example: Print 1 to 20


Step 1: Initialize X as 0,

Step 2: Increment X by 1,

Step 3: Print X,

Step 4: If X is less than 20 then go back to step 2
