C++ Information Hiding and Modular Programming

Separation of component interface and implementation enhances clarity and facilitates modular design.
Improved maintainability allows easier updates and revisions to individual components.
Enhanced reusability enables components to be utilized in different programs or contexts without modifications.
Portability refers to the ease of using components across various platforms or systems.

Object-Based Data Type Development in C++

Pre-condition and post-condition interplay determines the expected state before and after function execution.
Constructors ensure initial validity of objects, while destructors manage object cleanup without compromising state.
Contract-oriented approach emphasizes defining clear expectations and guarantees about function behavior.

Abstraction in Problem Solving

Effective abstraction aids in managing complex problems, simplifying analysis and solution development.
Promotes the creation of pseudocode, easing the transition from concept to implementation.

Abstract Data Types (ADT)

ADTs define the "what" instead of the "how," focusing on behavior rather than implementation specifics.
Specifications typically include interface definition but leave implementation details abstracted.

Function Parameter Passing

Passing by value creates a copy, ideal for small data types.
Passing by reference allows direct access to the original data, useful for large objects to avoid overhead.
Passing by const reference prevents modification while still allowing efficient access.

Member Functions and Data Access

Member functions can access private data members of their class, fostering encapsulation and internal data integrity.
Access is universal across all objects of the class, ensuring consistent data handling.

Encapsulation Practices

Avoid breaking encapsulation by minimizing exposure of implementation details and limiting privilege access.
Inappropriate use of friend functions can violate encapsulation principles.

Templating in C++

Templating is characterized by parameterization, allowing functions and classes to operate with generic types.

Item Data Type Restrictions

When using the isSmaller function, the Item data type must support the comparison operation defined within the function for expected behavior.
