Study Notes

Introduction to Programming

Programming involves planning and executing tasks to solve problems using a computer.
It entails writing instructions for a computer to follow specific actions based on data inputs.

Data Processing Cycle

Consists of steps where a computer receives data, processes it according to program instructions, displays outcomes, and stores results.

Program Development Process

First, clearly understand the problem, including expected inputs, processing requirements, and necessary outputs.
Develop detailed plans to solve the problem. Tools include:
- Algorithms or pseudocode
- Flowcharts
- Structure charts
Implementation involves writing the source code based on the detailed design.
Testing identifies and corrects errors (bugs) through debugging, which involves simulating the program's information flow.
Two types of testing:
- Black box testing examines outputs based on requirements without knowledge of internal workings.
- White box testing assumes complete program knowledge, ensuring every instruction and scenario is tested.
Documentation includes information on program requirements for users, like operating system and hardware specifications.
Maintenance ensures programs remain functional and updated with ongoing developments in the relevant field.

Programming Languages

A programming language consists of a vocabulary and grammatical rules to instruct a computer.
Each language has unique keywords and syntax.
Syntax refers to the rules for writing statements, while semantics pertains to their meanings.

Compilers and Interpreters

Compilers translate high-level programming languages into machine-readable binary code prior to execution.
Interpreters convert high-level instructions to machine-understandable code during runtime.
Programs must eventually be in machine language for computer comprehension.

Programming Paradigm

Procedural Programming: Involves sequential instructions that guide the computer incrementally, utilizing procedures or subroutines. Also known as imperative programming.
Object-Oriented Programming (OOP): Centers around objects as primary units of computation, allowing encapsulation of data and behaviors, exemplified by attributes and methods.
