KPIT Technologies Software Engineer Interview Questions and Answers

The four pillars of OOP are Encapsulation, Abstraction, Inheritance, and Polymorphism, essential for building robust software.

• Encapsulation: Bundling data and methods that operate on the data within a single unit (class). Example: A class 'Car' with attributes like 'speed' and methods like 'accelerate()'.

• Abstraction: Hiding complex implementation details and showing only the essential features. Example: A 'Payment...read more

The pillars of OOP are encapsulation, inheritance, polymorphism, and abstraction, forming the foundation of object-oriented programming.

• Encapsulation: Bundling data and methods that operate on the data within one unit (class). Example: A 'Car' class with properties like 'speed' and methods like 'accelerate()'.

• Inheritance: Mechanism to create a new class from an existing class, inheriting its properties and methods...read more

A solver is a tool or algorithm used to find solutions to mathematical or logical problems.

• There are different types of solvers such as linear solvers, nonlinear solvers, integer solvers, constraint solvers, etc.

• Examples of solvers include the Simplex algorithm for linear programming, Newton's method for nonlinear equations, and backtracking algorithm for constraint satisfaction problems.

Model-Based Design (MBD) is a methodology used in software engineering to create models of systems before implementing them in code.

• MBD helps in visualizing and designing complex systems before coding.

• It allows for simulation and testing of the system behavior before implementation.

• MBD can improve communication between different teams working on a project.

• Examples include using tools like Simulink for modeling and...read more

calloc and malloc are functions used in C programming to allocate memory dynamically.

• calloc is used to allocate and initialize a block of memory, setting all bytes to zero.

• malloc is used to allocate a block of memory without initializing its contents.

• Both functions return a pointer to the allocated memory, or NULL if the allocation fails.

Writing test cases involves identifying test scenarios, creating test data, and documenting expected results.

• Identify test scenarios based on requirements and user stories

• Create test data that covers all possible scenarios

• Document expected results for each test case

• Use a combination of manual and automated testing

• In case of test failures, identify the root cause and report it as a defect

• Defects go through a defect...read more
