Course Content

  • Introduction to Programming:
    • Definition and basic understanding
    • Programming as instructing a computer
    • Importance of specific instructions
  • Programming Languages:
    • Role as a middleman to translate instructions
    • Examples: Python, Java, HTML, CSS
    • High-level vs. low-level languages
  • Integrated Development Environment (IDE):
    • Tool for writing, running, and debugging code
    • Features like error checking and autofill
  • Syntax and Grammar in Programming:
    • Importance of following syntax rules
    • Syntax varies across languages
    • Example: Java vs. Python vs. JavaScript
  • Console and Print Statements:
    • Output text and information
    • Use of print statements for displaying information
  • Basic Mathematics in Programming:
    • Arithmetic operations: addition, subtraction, multiplication, division
    • Modulus operation
  • Strings and Concatenation:
    • Strings as sequences of characters
    • Concatenation to combine strings and numbers

Key Programming Concepts

  • Variables:
    • Definition and types (integers, Booleans, floats, strings, chars)
    • Importance and manipulation of variables
  • Conditional Statements:
    • If, else, and switch statements
    • Importance for decision-making in programs
  • Arrays:
    • Data structure for storing multiple values
    • Indexing and multidimensional arrays

Advanced Topics

  • Loops:
    • For loops, while loops, and do-while loops
    • Repeated execution of code blocks
  • Error Handling:
    • Types: Syntax, runtime, and logic errors
    • Debugging strategies
  • Functions:
    • Purpose and types (arguments and return values)
    • Built-in functions and creating custom functions
  • Importing Functions:
    • Use of libraries and packages to access external functions
  • Recursion:
    • Recursive functions and base cases
    • Importance in breaking down problems
  • Data Structures:
    • Arrays, array lists, dictionaries
    • Searching algorithms (linear and binary search)

Additional Learning

  • Pseudocode and Planning:
    • Importance of planning before coding
    • Methods: Flowcharts, chronological write-ups, feature planning
  • Choosing a Programming Language:
    • Based on task requirements (e.g., web design, scripting)
    • High-level vs. low-level considerations
  • Next Steps in Learning:
    • Self-study resources: Coding challenges, online courses
    • High school courses: AP Computer Science
    • Community involvement: GitHub, collaborations
