    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
