Notes

What is a Flowchart?

A flowchart is a graphical representation of an algorithm or process. It uses standard symbols and arrows to show the sequence of steps used to solve a problem.

💡 In Simple Words

A flowchart shows the steps of a solution visually so that the logic of a problem is easier to understand.

Real-World Example

🌍 Real World Example

Think about the process of getting ready for college: wake up → get ready → have breakfast → go to college. When these steps are shown using symbols and arrows, they form a simple flowchart.

Why is a Flowchart Used?

  • Makes the logic of a problem easier to understand.
  • Shows the sequence of steps clearly.
  • Helps in planning a program before coding.
  • Makes errors or missing steps easier to identify.
  • Helps explain a solution to others.

Flowchart in Problem Solving

A programmer can first develop an algorithm and then represent the same logic graphically using a flowchart.

PROBLEM ↓ ALGORITHM ↓ FLOWCHART ↓ PROGRAM ↓ OUTPUT

Simple Flowchart Example

The following example represents the logic for adding two numbers.

START ↓ INPUT A, B ↓ SUM = A + B ↓ PRINT SUM ↓ STOP
📌 Remember

An algorithm describes a solution using steps, while a flowchart represents those steps graphically.

Flowchart vs Algorithm

Algorithm Flowchart
Written step-by-step instructions. Graphical representation of the steps.
Focuses on logical instructions. Focuses on visual flow of the solution.
Can be written in simple language or pseudocode. Uses standard symbols and arrows.

Advantages of a Flowchart

  • Easy to understand and explain.
  • Provides a clear visual view of the solution.
  • Helps in program planning.
  • Useful for finding logical mistakes.
