Study Notes
Problem Solving & Procedures
- When solving a problem, an effective method or procedure should be identified.
- This procedure breaks the solution into simple steps that must be followed in order.
- A complex problem can be broken down into smaller sub-problems (top-down design/stepwise refinement).
- Sub-procedures contain commands to perform tasks.
- Modular programming divides the problem into sub-procedures using identifiers.
- Identifiers uniquely name variables, objects, and sub-procedures.
Programming Concepts
- Iteration is repeating a series of instructions (using loops).
- Conditional statements (if-then-else) perform different instructions based on conditions (Boolean tests).
- Object-oriented programming uses objects describing data (properties) and behavior (methods).
- Entities are objects or events.
Programming Paradigms
- Procedural/Structural programming uses procedures to interact and exchange data.
- Collections are data structures (e.g., arrays, linked lists) for storing, managing, and retrieving structured data in a program.
Data Representation
- Variables store values
- Variables each have a name
- Data types (e.g., strings, reals, booleans, integers, arrays) define the type of data a variable can hold
- Arrays organize data elements of the same type.
- One-dimensional arrays are linear arrangements.
- Parallel arrays are used to store different properties of an entity.
Algorithms and Searching
- Linear search and Binary search algorithms are used to search for elements in an array.
- Sorting algorithms (bubble sort, selection sort) arrange items in ascending or descending order.
- Collections (like arrays) are used for organizing and working with data.
Program Operations
- Efficiency is the amount of computer resources needed to complete operations.
- Correctness ensures the algorithm meets its intended specifications.
- Reliability ensures the consistent performance of the algorithm under specific conditions.
- Flexibility enables the algorithm to be modified for different purposes.
- Big O notation measures the algorithm's efficiency.
- Lists, arrays, and other containers store sequences of values.
Programming Languages
- Machine Language is the lowest-level language understood by computers.
- High-level programming languages use more user-friendly elements to manipulate computer instructions.
- Assembly languages use mnemonics (symbols) instead of binary code.
- Compilers translate high-level language to machine language once.
- Interpreters translate and execute high-level language statements one at a time, usually line by line.
- Variables store data values, constants represent unchanging values, operators perform actions, and objects are collections of data and actions.
Program Structure
- Global variables are accessible throughout the program.
- Local variables are limited to a specific part of a program.
- Collections (containers) store related data.
- Sub-programs (functions, procedures) encapsulate specific, logical tasks within a program.
- Code reuse leads to more efficient programming.
- Breaking a large program into smaller parts improves maintainability and organization.
- Software libraries contain pre-created sub-programs for easier development.
- Using collections improves performance and efficiency.
- Parameters/arguments and methods in programming are used to create reusable operations.
