IBM Interview Questions
What are the OPPs concepts?
Object-Oriented Programming (OOPs) has six fundamental concepts, which are:
- Object
- Class
- Inheritance
- Polymorphism
- Encapsulation
- Abstraction
What is a Constructor?
In object-oriented programming, a constructor is a special method that is automatically called when an object of the class is created. It is used to initialize the object’s state by assigning values to the object’s attributes or properties.
What is the difference between an interface and an abstract class?
Interface:- An interface is a blueprint for a class that defines a set of methods that must be implemented by any class that implements the interface.
Abstract: – An Abstract class is a class that cannot be instantiated and may contain one or more abstract methods that must be implemented by any subclass.
What are different types of Software testing?
Software testing is categorized into five types. Which are:
- Unit testing
- Integration testing
- System testing
- Acceptance testing
- Regression testing
What is the difference between static and dynamic binding?
| Static binding | Dynamic binding |
| Static binding is resolved at compile-time. | Dynamic binding is resolved at runtime. |
| In static binding, the method called is based on the type of the object reference. | While in dynamic binding, the method called is based on the actual type of the object. |
What is a deadlock in the operating system?
A deadlock is a situation where two or more processes are unable to proceed because they are waiting for each other to release resources.
What is an array?
An array is a data structure that stores a collection of values of the same type in conterminous memory locales. It’s a way of storing and accessing a group of data values by using a single variable name. Each element in an array is linked by an indicator, which is a numeric value that represents the position of the element in the array.
What is a lambda function in python?
A lambda function in python is a small anonymous function that can be defined without a name.
Syntax:
lambda arguments: expression
Here, arguments represent the arguments that are passed to the function and expression represents the operation that the function will perform. The result of the expression represents the operation that the function will perform. The result of the expression is then returned as the output of the function.
What is the difference between list and tuple?
| List | Tuple |
| List is a mutable datatype. | Tuple is an immutable datatype. |
| Lists are typically used when you need a collection of objects that can be modified, such as when you need to append or remove elements. | Tuples are typically used when you need a collection of objects that cannot be modified, such as when you need a collection to store a group of related values that will always remain the same. |
| List elements are enclosed with [] and separated with comma. | Tuple elements are enclosed with () and separated by comma. |
What is a mutable datatype?
In computer programming, a mutable datatype is a type of data that can be changed or modified after it has been created. This means that you can add, delete, or modified elements of the data structure without creating a new copy of the data.
What is a pointer?
Pointer is a variable that stores the memory address of another variable. Pointers provide a powerful and flexible way to manipulate data in memory, allowing for more efficient and precise memory allocation and data access. With pointers, you can easily modify the data stored in a variable or pass large data structures to functions without having to make copies of the entire data structure.
What is kernel in Operating system?
In an operating system, the kernel is the central component that manages the system’s resources and provides services to other parts of the system. It is the core of the operating system, responsible for controlling the hardware and software resources of the system, and for facilitating communication between the different components of the system.
What is the difference between struct and union?
In C programming language, a struct and a union are two ways to define a custom data type, but they have different characteristics.
A struct is a composite data type that groups together different variables with different data types under a single name. Each variable in the struct has its own memory location and can be accessed independently.
A union, on the other hand, is also a composite data type, but all of its members share the same memory location. This means that only one member of the union can be accessed at a time, and accessing a different member will overwrite the previous value.
What is the condition of deadlock?
A deadlock is a situation in a computer system where two or more processes are unable to continue executing because they are waiting for each other to release resources they need to proceed. Deadlocks can occur in multi-threaded or multi-process systems when the following four necessary conditions are met simultaneously:
- Mutual Exclusion: At least one resource is non-sharable, meaning only one process at a time can use it.
- Hold and Wait: A process holds at least one resource and is waiting for another resource that is currently being held by another process.
- No Preemption: Resources cannot be forcefully removed from a process that’s holding them.They can only be released voluntarily by the process that is holding them.
- Circular Wait: A cycle of processes exists in which each process is waiting for a resource held by the next process in the cycle.
What is the string?
A string is a sequence of characters that represents text or data. A string can contain letters, numbers, symbols, and whitespace characters, and can be represented as a sequence of bytes or unicode code points.
In many programming languages, a string is enclosed in quotation marks to distinguish it from other data types.
