    Study Notes

    Structured Programming Methods - Study Notes

    • Structured Programming Methods is a programming approach focused on organizing programs into logical blocks (procedures, functions, and subroutines) to enhance program readability and maintainability.
    • This approach is preferred over less structured methods that rely heavily on GOTO statements.
    • Procedures/Functions are modular blocks of code (subprograms) that perform a specific task. Data is passed to these functions via parameters.
    • Procedures return no value; Functions always return a value.
    • The use of procedures/functions enhance code organization, reusability, and testability.
    • Local variables are only accessible within the procedure/function where they are declared. This feature helps to prevent unintended side effects.
    • Global variables are accessible throughout the entire program, use them with caution.
    • Arrays are ordered collections of data items of the same type with a fixed size. The individual data items in an array can be directly accessed using their position number. This is called the subscript.
    • Linked Lists are a data structure that is an ordered collection of items linked from item to item. The items are not stored in consecutive locations but are linked using links (pointers).
    • Queues are a data structure based on the First-In, First-Out (FIFO) principle. Elements are added at one end (rear) and removed from the other (front).
    • Stacks are a data structure based on the Last-In, First-Out (LIFO) principle. Elements are added and removed from the same end (top).
    • Data structures like queues and stacks are widely used in programming for managing information logically and efficiently.
    • Sorting techniques are algorithms used to rearrange items in an array (or list) into a specific order (e.g., ascending or descending). Different sorting algorithms have their own characteristics and efficiency trade-offs.
    • Searching techniques are algorithms used to locate a particular item within a data structure like an array or a linked list. The efficiency of searching methods is also an important consideration.

    Data Structures (Queues, Stacks, Graphs, and Trees)

    • Graphs represent networks of elements (nodes) and their relationships (edges). Graphs can be cyclic or acyclic.
    • Trees are hierarchical data structures where each element has a single parent, unlike graphs where there can be multiple parents.
    • Binary Trees are a special type of tree where each node has at most two children.
