Study Notes

Introduction to Programming

Programming involves creating a sequence of instructions for computers, known as code.
Enables innovation and efficiency in solving global challenges.
Crucial for automating and managing data processes accurately.

Key Computer Programming Terms

A computer program comprises instructions that inform the computer's actions.
Programming language (PL): Written language utilized to construct programs, governed by grammar known as syntax.
Source code: The set of instructions written in a programming language that needs translation into machine language.

Language Types

Low-level languages: Machine-specific, cryptic, not human-readable; examples include machine and assembly languages.
High-level languages: Easier to understand with English-like syntax, capable of running across various systems; examples include Visual Basic, C++, and Java.
Language translation tools:
- Assembler: Converts assembly language to machine code.
- Interpreter: Translates and executes one line at a time.
- Compiler: Translates entire code at once, providing error diagnostics.

Programming Paradigms

Procedure-oriented programming: Focuses on tasks; programmers guide step-by-step processes.
Object-oriented programming: Centers on objects with attributes and methods; promotes reusability and easier problem-solving.

Program Development Cycle

Entails phases for orderly program development including:
- Requirement Analysis: Identifying system requirements and user needs.
- System Design: Outlining the algorithm for problem-solving using pseudocode or flowcharts.
- Coding: Writing the actual program in a chosen language while adhering to syntax.
- Testing and Debugging: Verifying functionality through various tests including desk-checking and alpha testing.
- Documentation and Maintenance: Creating comprehensive documentation for usage and ongoing support.

Error Types in Programming

Syntax Error: Incorrect statement structure; typically the most common error.
Run-time Error: Occurs during program execution, leading to crashes.
Logical Error: Flaws in the logic resulting in unexpected or incorrect behavior.

Importance of Documentation

Detailed descriptions serve as guides for users and maintainers of software.
Maintenance ensures the software remains functional and updated.
