BNY Software Engineer Interview Questions and Answers

Polymorphism is the ability of an object to take on many forms. Types include compile-time, runtime, and ad-hoc polymorphism.

• Compile-time polymorphism is achieved through function overloading and templates.

• Runtime polymorphism is achieved through inheritance and virtual functions.

• Ad-hoc polymorphism is achieved through operator overloading and function templates.

• Polymorphism allows for code reusability and flexibility in object-oriented programming.

• Example: A shape class with...read more

White Box testing is a software testing technique that examines the internal structure and implementation of the system.

• White Box testing is also known as Clear Box testing, Glass Box testing, or Structural testing.

• It involves testing the code, logic paths, and internal components of the software.

• Test cases are designed based on the knowledge of the internal structure of the system.

• It helps in identifying errors, code coverage, and optimizing code performance.

• Examples of whit...read more

Software testing is the process of evaluating a software application or system to ensure it meets the specified requirements.

• Software testing is done to identify defects or errors in the software.

• It involves executing the software with test cases and comparing the actual results with expected results.

• Different types of testing include unit testing, integration testing, system testing, and acceptance testing.

• Testing can be manual or automated, depending on the complexity and r...read more

Object oriented programming is a programming paradigm based on the concept of objects, which can contain data and code.

• Objects are instances of classes, which define the structure and behavior of the objects.

• Encapsulation, inheritance, and polymorphism are key principles of object oriented programming.

• Example: Inheritance allows a subclass to inherit attributes and methods from a superclass.

Software is a set of instructions that tells a computer what to do.

• Software is a collection of programs, data, and instructions that tell a computer how to perform specific tasks.

• It can be categorized into system software, application software, and middleware.

• Examples of software include Microsoft Office, Adobe Photoshop, and Google Chrome.
