Study Notes
Computer Operations
- The computer performs three major operations: Input, Processing, and Output
Programming Languages
- A programming language has its own set of rules, symbols, and syntax
- Compiler: translates high-level language code into machine language
- Interpreter: translates programming code one statement at a time
Key Aspects of Programming Logic
- Variables: named memory locations used to store data during program execution
- Data types: define the type of data stored in variables
- Operators: symbols used to perform operations on one or more operands
- Control structures: used to determine the flow of execution of the program
- Functions: reusable pieces of code that perform a specific task
- Syntax: set of rules that define how programs in a programming language must be written
Types of Errors
- Syntax errors: incorrectly written code that does not follow syntax rules
- Run-time errors: errors that arise during program execution
- Logical errors: incorrect output due to incorrect order of instructions
Problem Solving
- Identify the problem
- Understand the problem
- Identify alternative solutions
- Select the best solution
- List the instructions to solve the problem
- Evaluate the solution
Program Development Cycle
- Understand the problem
- Plan the logic
- Code the program
- Translate the program into machine language
- Test the program
- Put the program into production
- Maintain the program
Programming Paradigms
- Procedural programming: divides program structure into small parts called functions, procedures, or methods
- Object-oriented programming (OOP): divides program structure into small parts called objects
- OOP features:
- Access specifiers (private, public, protected)
- Data hiding for security
- Overloading (different functionality with the same function name)
- Inheritance (reusing code with minor modifications)
