PPS Assignment: 5, Presentation: 8

Design a simple C program and corresponding flowchart that simulates a billing system for a mini grocery store using basic if-else statements and C syntax.

Assignment Instructions (5 Marks)

• Design a flowchart (using draw.io or hand-drawn and scanned) that:

  • Takes input for item name, quantity, and unit price.

  • Calculates total price.

  • Applies discount logic:

    • If total > 1000, apply 10% discount.

    • If total > 500 but <= 1000, apply 5% discount.

    • Otherwise, no discount.

  • Outputs final bill amount.

• Write a C program to:

  • Take 3 inputs: item name, quantity, unit price.

  • Calculate and apply discount.

  • Print:

    • Item name

    • Quantity

    • Unit price

    • Total price

    • Discount applied

    • Final amount

• Submit both:

  • The .c file

  • The flowchart in PDF or image format

    Presentation Guidelines (8 Marks)

    Each student (or pair) will record or deliver a 3–5-minute presentation covering:

    1. Flowchart Explanation – How the logic flows (2 Marks)

    2. Code Walkthrough – Variable declaration, input/output, decision-making (2 Marks)

    3. Discount Logic Justification – Explaining the if-else structure (2 Marks)

    4. Improvements or Extensions – Bonus: any creative extension, like multiple item input, better UI (2 Marks)

       Bonus Twist (Optional for Extra Credit):

       • You can choose another real-life scenario (e.g., movie ticket booking, electricity billing) using similar if-else logic and flowchart design.
