Other Logic Development Techniques – Algorithm and Flowchart Based on Programming

Developing programming logic is one of the most important skills for every BCA student. Before writing any program, it’s necessary to think logically and represent that logic using proper techniques such as Algorithms and Flowcharts. In this article by BCA School, we’ll explore various logic development techniques that help in building correct and efficient programs.

🔹 What is Logic Development?

Logic Development means the ability to think and plan the steps required to solve a problem using a computer. It involves breaking a problem into smaller parts, understanding the flow of data, and deciding the correct sequence of operations.

Without strong logic, it’s difficult to write error-free programs. That’s why programmers use structured methods such as Algorithm and Flowchart to develop logic before coding.

🔹 Logic Development Techniques

There are several techniques used for developing logic in programming. Two of the most common and important are:

1️⃣ Algorithm-Based Logic Development

An Algorithm is a step-by-step method to solve a problem. It represents the logical sequence of instructions in human-readable form.

✅ Example: Algorithm to Check Even or Odd Number

Step 1: Start
Step 2: Read number n
Step 3: If n % 2 == 0 then
           Print "Even"
        Else
           Print "Odd"
Step 4: Stop

Explanation: In this algorithm, the logic is clearly defined step by step. It helps programmers easily convert these steps into program code.

2️⃣ Flowchart-Based Logic Development

A Flowchart is a diagrammatic representation of an algorithm. It uses symbols and arrows to represent the flow of control.

✅ Example: Flowchart for Even-Odd Check

      Start
        ↓
   Input n
        ↓
   Is n % 2 == 0 ?
     ↙        ↘
   Yes         No
   ↓            ↓
 Print "Even"  Print "Odd"
        ↓
       Stop

Explanation: The flowchart makes the logic visual and easier to understand for beginners. It clearly shows the decision-making process using a diamond (decision symbol).

🔹 Advantages of Algorithm and Flowchart Techniques

• Helps to plan and organize the solution logically.
• Reduces chances of errors in the final program.
• Improves understanding of problem-solving structure.
• Acts as a reference during coding and debugging.
• Helps in teamwork by providing a common understanding of program logic.

🔹 Steps for Developing Logic in Programming

1. Understand the problem statement properly.
2. Identify the required inputs and expected outputs.
3. Write an algorithm for the solution.
4. Draw a flowchart to visualize the logic.
5. Test the logic using dry run before actual coding.
6. Convert logic into program code (C, Python, Java, etc.).

🔹 Example Problem: Find the Largest of Three Numbers

Algorithm:

Step 1: Start
Step 2: Read three numbers A, B, C
Step 3: If A > B and A > C, Print "A is Largest"
        Else If B > C, Print "B is Largest"
        Else Print "C is Largest"
Step 4: Stop

Flowchart:

        Start
          ↓
      Input A, B, C
          ↓
     Is A > B and A > C ?
      ↙             ↘
    Yes              No
   ↓                  ↓
Print A         Is B > C ?
                     ↙     ↘
                   Yes      No
                   ↓         ↓
               Print B     Print C
                     ↓
                    Stop

🎯 Conclusion

Logic development is the foundation of programming. Using Algorithm and Flowchart techniques makes programming easier and error-free. As a BCA student, practicing these logic-building methods will strengthen your problem-solving skills and make you a better programmer.
