Basic Programs

This section is the starting point for programming practice. Focus on input/output, variable handling, and step-by-step logic before moving to advanced topics.

Learning Goals

• Build confidence with small executable programs.
• Understand how inputs transform into outputs.
• Practice clean code structure and validation habits.

Topics

• Hello World
• User Input Display
• Arithmetic Operations
• Type Conversion
• Data Types
• Ascii Value Of Character
• Basic Arithmetic
• Swap Variables
• Swap Without Temporary Variable
• Swap Three Numbers
• Array Element Swap

Practice Strategy

1. Run each program with at least 3 different inputs.
2. Add one invalid input test per program.
3. Write short notes: logic, edge case, and expected output.
