Algorithms and Flowcharts

Computer Programming की शुरुआत किसी Problem को समझने और उसका Solution तैयार करने से होती है। Algorithm तथा Flowchart Problem Solving के दो महत्वपूर्ण Tools हैं जिनका उपयोग Program लिखने से पहले Logic Design करने के लिए किया जाता है।

Introduction

जब किसी Problem का Solution Computer के माध्यम से करना होता है तब सबसे पहले Steps को Define किया जाता है। इन Steps को Algorithm के रूप में लिखा जाता है तथा उन्हें Graphical Form में प्रदर्शित करने के लिए Flowchart का उपयोग किया जाता है।

Algorithm तथा Flowchart Programming की Foundation माने जाते हैं क्योंकि ये Program Development Process को सरल बनाते हैं।

Definition of Algorithm

Algorithm किसी Problem को Solve करने के लिए Step-by-Step Instructions का एक Finite Sequence होता है।

Algorithm = Finite Sequence of Steps

Characteristics of Algorithm

• Input Defined
• Output Defined
• Finite Steps
• Unambiguous Instructions
• Effective Execution
• Correctness

Example of Algorithm

Algorithm to Add Two Numbers:

1. Start
2. Input A and B
3. Calculate Sum = A + B
4. Display Sum
5. Stop

Advantages of Algorithm

• Easy Problem Analysis
• Language Independent
• Easy Debugging
• Improves Program Design

Limitations of Algorithm

• Time Consuming for Large Problems
• No Visual Representation
• Complex Logic May Be Difficult

Definition of Flowchart

Flowchart किसी Algorithm का Graphical Representation होता है जिसमें विभिन्न Symbols का उपयोग करके Program Logic को प्रदर्शित किया जाता है।

Flowchart = Graphical Representation of Algorithm

Common Flowchart Symbols

Flowchart Example

Addition of Two Numbers Flow:

1. Start
2. Input A and B
3. Process A + B
4. Display Result
5. Stop
