Introduction to Problem Solving Programming
✓ Steps for problem solving.
✓ Introduction of Algorithm.

Topic: Introduction to Problem Solving and Programming

Problem Solving in Computers

• A problem is a task we want the computer to do (example: calculating marks, preparing bills, searching data).
• To solve a problem using a computer, we must give clear instructions in the correct order.

Steps for Problem Solving

1. Understanding the Problem
   • Read the problem carefully.
   • Find out what is given (input) and what is required (output).
   Example: If the problem is to find the average of 3 numbers → Input = 3 numbers, Output = average.
2. Making a Plan (Algorithm/Flowchart)
   • Decide the steps to solve the problem.
   • Represent it in algorithm (stepwise English instructions) or flowchart (diagram).
3. Writing the Program
   • Use a programming language (like Python, C, Java) to convert steps into code.
4. Testing the Program
   • Run the program with sample data to check for errors.
5. Debugging
   • Find and correct mistakes (errors) in the program.
6. Documentation and Maintenance
   • Write explanations (comments).
   • Update program when needed.

Introduction of Algorithm

Definition:

• An algorithm is a set of step-by-step instructions to solve a problem.
• It is written in simple English, not in computer code.

Features of a Good Algorithm:

• Clear and simple (easy to understand).
• Finite steps (must end after some steps).
• Correct (gives the right answer).
• Effective (solves the problem in limited time).

Example Algorithm: Find the sum of two numbers

1. Start
2. Input first number (A)
3. Input second number (B)
4. Add A and B → Store in SUM
5. Display SUM
6. Stop

Key Points to Remember – Problem Solving

• Problem solving = stepwise process to find a solution.
• Steps: Understand → Plan → Program → Test → Debug → Document.
• Algorithm = Step-by-step instructions written in simple language.
• Algorithms are the first step before coding.
