Study Notes
Flowcharting
- A flowchart visually represents the sequential steps needed to solve a problem
- Terminal symbols mark the program's beginning and end
- Processing symbols indicate calculations and comparisons
- Preparation symbols initialize variable values
Flowchart Structures
- Sequence: Processes proceed linearly from one symbol to the next
- Repetition: Loops execute operations repeatedly until a condition is satisfied.
- Selection: Provides branching paths based on conditional outcomes.
Programming Fundamentals
- Structure Design: Breaking down problems into smaller, manageable subproblems
- Object-Oriented Design: A prevalent methodology where programs consist of interacting objects
- Source Program: Code written in a high-level language, understandable by humans.
- Machine Language: A low-level language directly understood by computers.
- Preprocessor Directives: Statements starting with '#' that provide instructions to the compiler.
Program Compilation and Execution
- Compiler: Checks source program for syntax errors and translates it into machine language.
- Object Program: Machine language equivalent of a high-level language program.
- Library: Storage location for pre-written code modules.
- Linker: Combines the object program with necessary library programs to create an executable code.
- Loader: Places an executable program into main memory for execution.
Reserved Words and Identifiers
- Reserved Words: Keywords used by the programming language (e.g., "if," "else," "while")
- Identifiers: Names given to variables, constants, and functions within a program.
Additional Flowchart Symbols
- Predefined: Represents a subprogram or subroutine.
- On-Page Connector: Continues a process on the same page.
- Off-Page Connector: Indicates a connection to another page.
- Flowline: Connects symbols, demonstrating the direction of the program flow.
- Input/Output: Symbols representing actions like receiving user input or displaying output.
- Decision: A diamond shape indicating a condition, leading to different paths.
Flowcharts
- A visual representation of the steps involved in solving a problem
- Uses symbols to represent different actions and decisions
- Essential for understanding complex algorithms and program logic
Flowchart Symbols
- Terminal: Represents the start and end of a program
- Processing: Represents calculation and comparison operations
- Preparation: Initializes variables with starting values
- Input/Output: Used for data entry and display of results
- Decision: Checks conditions, allowing for branching based on true or false outcomes
- Predefined Process: Represents a pre-written subroutine or function
- On-Page Connector: Continues the flow of the program within the same page
- Off-Page Connector: Indicates a connection to a separate page
- Flowlines: Arrows that show the direction of the flow within the flowchart
Programming Fundamentals
- Sequence: Program steps execute one after another in a linear order
- Repetition: Loops allow for repeated execution of a block of code based on a condition
- Selection: Branching logic allows the program to choose alternative paths based on conditions
- Structure Design: Breaking down complex problems into smaller, more manageable modules
- Object-Oriented Design: A popular programming methodology that views programs as collections of interacting objects
Programming Languages
- Source Program: Written in a high-level language, understandable to humans
- Machine Language: The low-level language understood by computers
- Preprocessor Directives: Statements that begin with '#' and provide instructions to the compiler
- Compiler: Translates the source code into machine language (object code)
- Object Program: The machine language version of the source code
- Library: A collection of pre-written functions and modules that can be reused
- Linker: Combines the object program with necessary library components to create an executable file
- Loader: Loads the executable program into main memory for execution
- Reserved Words: Keywords that have special meaning in the programming language and cannot be used as identifiers
- Identifiers: Names given to variables, constants, functions, and other entities within a program
