Unit 773: Comprehensive Introduction to Programming

1. Introduction to Programming

• Definition of programming
• Importance and applications of programming
• Overview of different programming languages (e.g., Python, Java, C++)
• Basic programming concepts: algorithms, syntax, semantics

2. Variables and Data Types

• Declaring and initializing variables
• Common data types:
  • Integers
  • Floating point numbers
  • Strings
  • Booleans
• Type conversion and casting
• Basic data manipulation and operations

3. Operators and Expressions

• Arithmetic operators: +, -, *, /, %, **
• Comparison operators: ==, !=, >, <, >=, <=
• Logical operators: and, or, not
• Operator precedence and associativity
• Forming and evaluating expressions

4. Control Structures

• Conditional statements:
  • if
  • else if / elif
  • else
• Looping constructs:
  • for loops
  • while loops
• Nested conditions and loops
• Practical examples and use cases

5. Functions and Methods

• Defining functions
• Parameters and arguments
• Return values
• Scope of variables (local vs global)
• Methods as functions associated with objects
• Benefits of modular programming and code reuse

6. Arrays and Lists

• Introduction to arrays and lists as data structures
• Declaring and initializing arrays/lists
• Accessing elements via indexing
• Common operations: adding, removing, updating elements
• Iterating over arrays/lists
• Use cases and applications

7. Object-Oriented Programming (OOP)

• Introduction to OOP concepts
• Classes and objects
• Attributes and methods
• Encapsulation and data hiding
• Inheritance and subclasses
• Polymorphism and method overriding
• Simple OOP example

8. File Handling

• Reading from files
• Writing to files
• File modes (read, write, append)
• Handling exceptions during file operations
• Practical examples

9. Debugging and Troubleshooting

• Common types of errors (syntax, runtime, logical)
• Debugging techniques:
  • Code review
  • Print statements
  • Using debuggers/IDE tools
• Problem-solving strategies
• Best practices for writing error-free code
