NCR Corporation Interview Questions and Answers

Dependency injection is a design pattern used to remove hard-coded dependencies and make code more modular and testable.
Dependency injection involves injecting dependencies into a class rather than having the class create them itself.
This allows for easier testing and swapping out of dependencies.
There are three types of dependency injection: constructor injection, setter injection, and interface injection.
Example...
Virtual keyword is used to declare a method in a base class that can be overridden in a derived class. Override keyword is used in the derived class to override the implementation of the virtual method.
Virtual keyword is used in the base class to declare a method that can be overridden in the derived class

Indexes in SQL are used to improve the performance of queries by allowing faster data retrieval.
Indexes are created on one or more columns of a table.
They work like a book index, allowing the database to quickly find the data.
Indexes can be clustered or non-clustered.
Clustered indexes determine the physical order of data in a table.
Non-clustered indexes create a separate structure to store the index data.
Indexes s...
Extension methods are static methods that allow adding new functionality to existing types without modifying the original type.
Extension methods are defined in a static class.
They must be declared with the 'this' keyword before the first parameter.
They can be called as if they were instance methods of the extended type.
Extension methods can be used to add functionality to built-in types or custom types.
Example: ad...
Routing in MVC is done through the use of routes, which map URLs to controller actions.
Routes are defined in the RouteConfig.cs file in the App_Start folder
Routes consist of a URL pattern and a corresponding controller action
Routes can also include optional parameters and constraints
Routing is done through the use of the ASP.NET routing engine
Routing can be customized by creating custom route handlers
Filters in MVC are used to intercept and modify HTTP requests and responses.
Filters can be used to implement authentication and authorization.
They can also be used for caching and logging.
Examples of filters include AuthorizationFilter, ActionFilter, and ExceptionFilter.
Singleton design pattern restricts the instantiation of a class to a single instance and provides a global point of access to it.
Used when only one instance of a class is required throughout the system
Provides a global point of access to the instance
Implemented using a private constructor, static method, and static variable
Example: Logger class, Database connection class
Program to find the second largest element from a 4-digit number
Convert the number to a string and split it into an array of characters
Sort the array in descending order
Return the second element of the array
Understanding pointer manipulation in C/C++ can lead to unexpected outputs, especially with arrays and dereferencing.
Pointers hold memory addresses, allowing direct access to variables.
Dereferencing a pointer gives the value at the address it points to.
Modifying a value through a pointer affects the original variable.
Example: int a = 5; int *p = &a; *p = 10; // a is now 10.
Pointer arithmetic can lead to access...
I would follow the standard protocol for handling a dead machine.
I would first confirm that the machine is indeed dead and not just malfunctioning.
I would then follow the standard protocol for handling dead machines, which may include checking for any visible damage or signs of wear and tear.
If necessary, I would consult with other engineers or technical experts to determine the best course of action for repairing...

Liskov Substitution Principle (LSP) - Objects of a superclass should be replaceable with objects of its subclasses without affe...

OOPs stands for Object-Oriented Programming. It is based on four main pillars: Inheritance, Encapsulation, Abstraction, and Polymorphism.
Inheritance: Allows a class to inherit properties and behavior from another class. Example: class B extends class A.
Encapsulation: Bundling data and methods that operate on the data into a single unit. Example: using private access modifiers to restrict access to certain data.
Abstract...
