Study Notes
Programming Logic
- Programmers write code in programming languages to create applications.
- Programs are a sequence of instructions for computers to perform.
- Programmers need to consider how input, processing, and output are defined.
- Programs often have branches and loops, and may contain duplicate steps.
Flow Charts
- Flow charts are visual representations of program sequences.
- They help to understand the program's structure and identify duplicates.
- Using flow charts enables writing more compact and efficient code.
Pseudocode
- Pseudocode is a way to represent code blocks before writing in a specific language.
- It uses comments and structures like subroutines, conditional statements, and variables.
- Subroutines can be called and return to their calling point.
Programming Languages
- The choice of programming language depends on the program type, developer experience, and target devices.
- Each language has its syntax, built-in functions, and features.
Programming Language Categories
- Compiled languages: code is translated into machine code before execution, often faster but platform-specific.
- Examples: C++, C#, COBOL, PASCAL
- Interpreted languages: code is executed within an interpreter, often slower but more platform-independent.
- Examples: JavaScript, Perl, Python
- Query languages: used to retrieve specific data from a dataset, do not need to be compiled.
- Example: SQL
Assembly Language
- An assembly language represents machine code in human-readable form.
- It is specific to a hardware architecture and difficult to follow.
- It is used by experts for specific problems.
Markup Languages
- Markup languages are used to structure and define data in a document.
- They use nested tags to describe content and meaning.
- Examples: HTML, XML
