Study Notes
Problem-Solving Process
- Problem-solving involves defining the problem, designing a solution, writing a program, compiling, debugging, testing, documenting, and maintaining the program.
- The divide and conquer principle helps break down problems into manageable steps, making them easier to solve.
Algorithm Definition
- An algorithm is a well-defined procedure or set of instructions aimed at solving a problem.
- The initial step in any algorithm is defining the problem by recognizing the need for pertinent information.
Flowchart Usage
- Flowcharts visually represent the sequence of steps in an algorithm, using recognizable symbols for clarity.
- They serve as a graphical tool for programmers to illustrate program operations.
Documentation Importance
- Documentation encompasses written descriptions and explanations of programs and is crucial for successful data processing applications.
- Proper documentation aids programmers and system analysts in modifying existing programs and procedures.
- The process of documentation is ongoing, starting from the initial request for system information.
Maintenance Significance
- Maintenance involves updates and modifications to programs based on system requirements.
- Quick resolution of detected issues, such as data not being saved correctly, is essential to prevent larger problems in business operations.
Machine Language
- Advantages: Runs very fast as no translation is needed for execution by the CPU.
- Disadvantages: Difficult to program; requires detailed knowledge of hardware. Programs must be rewritten for different computer types and are hard to debug.
Low-Level Language Execution
- Low-level languages, such as assembly language, provide fine control over hardware operations but can be tricky to debug and maintain.
- They generally offer faster execution than high-level languages.
Interpreters vs. Compilers
- An interpreter translates high-level language code into machine code at runtime, offering immediate execution and avoiding lengthy compilation processes.
- Examples of interpreted languages include LISP, BASIC, Java, and Python.
Object-Oriented Programming (OOP)
- OOP focuses on creating software as a network of interacting objects, emphasizing modular design.
- Key Concepts:
- Objects: Instances of classes with defined boundaries and characteristics.
- Classes: Blueprints for creating objects, detailing behaviors, and attributes.
OOP Principles
- Abstraction: Allows viewing problems at varying detail levels based on context.
- Encapsulation: Hides internal details of objects from external interaction, promoting better organization.
Popular OOP Languages
- Well-known object-oriented programming languages include Java, C++, C#, Ruby, and Python.
