Study Notes

Programming Concepts

Sequence: Represents a series of instructions executed in a specific order, crucial for procedural programming.
Assignment: Involves assigning a value to a variable using the equal sign (=), which establishes a memory reference for future operations.
Condition: A logical expression that resolves to true or false, used for decision-making in programming (e.g., age > 19).
Selection: A control structure for making decisions, allowing branching paths based on conditions. Common structures include IF, ELSE, and ELSEIF.
Iteration: Executes a set of instructions repeatedly, commonly referred to as loops, facilitating tasks that require repeated actions.

Programming Efficiency

Efficiency: Refers to the program's ability to perform tasks using minimal resources (time, processing power). It evaluates whether the execution is linear or utilizes conditional statements to optimize performance.
Maintainability: The ease with which code can be read, understood, and modified. Clear, well-structured code helps prevent errors during updates, thereby ensuring that changes do not disrupt interdependent modules.
Reliability: The code's robustness in handling unexpected input values. Reliable programs execute tasks accurately and consistently. Testing and addressing usability concerns enhances reliability, allowing for proactive error management.
