Flowchart & Flowchart to Find Largest Among Three Numbers

Flowchart is a diagrammatic/graphical representation of an algorithm that uses standard symbols (like ovals, rectangles, diamonds, and arrows) to show the step-by-step sequence of operations to solve a problem.

Key Symbols Used

• Oval → Start / Stop (Terminal)
• Parallelogram → Input / Output
• Rectangle → Process
• Diamond → Decision (Yes/No)
• Arrow → Flow of control

Flowchart to Find the Largest Among Three Numbers (A, B, C)

Step-by-step logic:

• Start → Input three numbers A, B, C
• If A > B, then compare A with C
  • If A > C → A is largest
  • Else → C is largest
• If B ≥ A, then compare B with C
  • If B > C → B is largest
  • Else → C is largest
• Stop

Conclusion: This flowchart uses nested decision boxes to compare three numbers and determines the largest by eliminating one number at each comparison step.
