Dependency Injection is a design pattern that allows for the decoupling of components in software development.

• Promotes loose coupling by injecting dependencies rather than hardcoding them.

• Improves testability by allowing mock objects to be injected during testing.

• Facilitates easier maintenance and scalability of code.

• Example: In a web application, a service class can be injected into a controller instead of being ...read more

OOPs concepts are fundamental principles in software design that promote code reusability and modularity.

• Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).

• Inheritance: Mechanism to create a new class using properties and methods of an existing class (e.g., a 'Dog' class inheriting from an 'Animal' class).

• Polymorphism: Ability to present the same interface for differe...read more

R1 release milestones are key events or goals that need to be achieved before the initial release of a product or software.

• R1 release milestones typically include completing all planned features, passing all necessary tests, and fixing any critical bugs.

• Examples of R1 release milestones may include code freeze, completion of user acceptance testing, and finalizing documentation.

• These milestones help ensure that th...read more

Polymorphism in C++ allows objects of different classes to be treated as objects of a common superclass.

• Polymorphism allows for functions to be called on objects of different classes through a common interface.

• Examples include function overloading, virtual functions, and inheritance.

• Dynamic polymorphism is achieved through virtual functions and inheritance.

• Static polymorphism is achieved through function overloadi...read more

Count the occurrences of each character in a given string and display the results in a formatted manner.

• Use a dictionary to store character counts.

• Iterate through the string and update counts for each character.

• Example: For 'Aaabbcc', the counts are: a-3, b-2, c-2.

• Consider case sensitivity if required (e.g., 'A' vs 'a').

• Output can be formatted as a string or printed directly.

Maintaining warehouse activity requires proper organization and management.
