A pointer is a variable that stores the address of another variable. It is used to point to the variables indirectly. It makes it possible to manipulate the values.
A memory leak occurs when objects available in a heap are not utilized. The garbage collector fails to remove it from memory. Hence these objects are kept in the memory unnecessarily. Memory leaks can lead to performance issues and are bad for the application's health.
Garbage collection is a memory management mechanism. An algorithm automatically detects the unused objects in the memory and deletes them.
The most commonly used garbage collection algorithm is Mark and Sweep algorithm.
Objects that are dynamically created are stored in the heap memory. If objects are created without management, the memory will exhaust, crashing the system.
Mark and Sweep algorithm is a garbage collection algorithm. It works in two phases.
In the first phase, the algorithm detects the unused objects in the memory, while in the second phase, these objects are removed from the memory to reclaim the wasted space.
Pointers that are not initialized with a valid address are called dangling pointers. It occurs during the object destruction phase. The object is destroyed from memory, but the pointer's address is not changed.
The process when a function calls itself directly or indirectly is called Recursion and the corresponding function is called a Recursive function.
A data type is characteristic of the data. It helps the compiler understand how the programmer intends to use the data.
The malloc() function stands for memory allocation. It is a function that is used to allocate a block of memory dynamically.
Example:
ptr = (cast-type*) malloc(bite-size);
The string is a data type. It is used to represent a sequence of characters.
| Language | Keyword | Example |
|---|---|---|
| C | char | 'A' |
| C++ | string | "Hello World" |
| Java | string | "Hello World" |
| Python | str() | "Hello world" |
An integer is a data type. It is used to represent numbers.
| Language | Keyword |
|---|---|
| C | int |
| C++ | int |
| Java | int |
| Python | int |
The array is a collection of similar elements stored in the contiguous memory block. The data stored in the memory can be accessed by index. Arrays are used to store large amounts of data in the memory.
There are eight primitive data types in Java. These data types have no additional methods. It only mentions the size and type of the variable value.
| int | Integer |
|---|---|
| It is a primitive data type. | It is a wrapper class |
| It has no additional methods | It has additional methods and flexibility for storing and manipulating the data. |
| int is not a class. | An integer is a class |
The bootloader, also known as the boot manager, is a program essential for booting a computer. It places the computer Operating System into the memory.
| Interpreter | Compiler |
|---|---|
| Translates one line of code at a time. | It scans the entire piece of code and converts it into machine code. |
| It is faster than a compiler in analyzing the program. | Although it is slower to analyze the program. But the overall execution time of the compiler is faster than the interpreter. |
| They are memory efficient. | As the compiler generates object code, it is less memory efficient than the interpreter. |
| Examples: Python, Ruby | Examples: C, C++, Java |
OOP stands for Object-Oriented Programming. It is about writing code in functions and procedures. The idea is about writing code in a minimalistic way that reuses code. The OOP follows:
Abstraction is the concept of object-oriented programming that shows only essential attributes while hiding the unnecessary data and implementation from the end-user.
Inheritance is a mechanism that allows one object to acquire all the characteristics and properties of another object. A class used for inheritance is called the base class or superclass, while the class that inherits is called a derived class or subclass.
It can be understood from a simple natural example - The son inherits all the properties and characteristics of his parents. You can create multiple objects using the template of parent objects.
Encapsulation is a way of protecting the data from outside access. It is done by wrapping it under a single program or function.
The data in an encapsulated class is hidden from other classes by declaring the variables of a class as private.
Polymorphism means taking multiple forms. The object in the program can act in different ways depending on the message or the event occurring.
A very good example of polymorphism is that a man can have different roles like father, son, or uncle yet he is the same person.
A constructor is used to initialize the state of an object. It is similar to the method. Every time a class is instantiated, a constructor is used for it. During the instantiation, the memory required for the object is allocated.
There are 2 types of constructors in Java:
Destructor is used to destroy the objects that are created while the class was instantiated. It is a special method that gets called when the object lifecycle comes to an end. It can remove the object from the memory and reclaim the space.
The destructor also releases any locks held by the object and closes the database connections.
No, you cannot override a constructor in Java. The constructor is similar to a method because it does not work like the Java method. If you try to call a super class's constructor in a subclass, the compiler treats it as a method and will throw a compilation error.
Constructor overloading can be defined as the concept of having multiple constructors with different parameters so that every constructor can perform a different task.
In Java, these constructors must have unique signatures and for error-free compilation different set of arguments must be passed to the constructor.
Example:
Input:
public class Employee {
int uid;
String name;
// Default constructor
Employee() {
System.out.println("This is a default constructor");
}
// Parameterized constructor
Employee(int i, String n) {
uid = i;
name = n;
}
public static void main(String[] args) {
// Object creation using the default constructor
Employee s = new Employee();
System.out.println("\nDefault Constructor values: \n");
System.out.println("Employee uid: " + s.uid + "\nEmployee Name: " + s.name);
System.out.println("\nParameterized Constructor values: \n");
// Object creation using the parameterized constructor
Employee employee = new Employee(10, "John");
System.out.println("Employee uid: " + employee.uid + "\nEmployee Name: " + employee.name);
}
}
Output:
This is a default constructor
Default Constructor values:
Employee uid: 0
Employee Name: null
Parameterized Constructor values:
Employee uid: 10
Employee Name: John
A virtual function is a member function that is declared in the base class and it is overridden by the derived class. The virtual function helps in achieving runtime polymorphism. Rules to keep in mind for virtual functions:
DML is also known as Data Manipulation Language. These statements are used to manipulate the database objects inside the database.
Following are commands in DML:
DDL is also known as Data Definition Language. These statements are used to define or modify objects in the database.
Following are commands in DDL:
Data structures are ways to organize and store data (like arrays, linked lists, stacks, and queues), while algorithms are step-by-step procedures to solve problems. Both are fundamental for writing efficient code and solving technical challenges.
OOPs (Object-Oriented Programming) concepts include encapsulation, inheritance, polymorphism, and abstraction. These principles help in organizing code and promoting reusability.
An HTML document starts with <!DOCTYPE html>, followed by <html>, <head> (contains metadata), and <body> (contains the content). Elements like headings, paragraphs, links, and tables are placed within the body.
Operating systems manage hardware and software resources, provide user interfaces, and enable the execution of programs by acting as an intermediary between the user and the hardware.
Networking refers to connecting computers and devices to share information and resources. It is essential for enabling communication, data sharing, and internet connectivity in modern software applications.
Python basics include understanding data types, variables, control structures (if-else, loops), functions, lists, and basic file operations.
Selenium is an open-source tool for automating web browsers. It is widely used for testing web applications by simulating user actions and verifying expected outcomes.
Both Java and C# are object-oriented programming languages. Java is platform-independent and widely used for web and enterprise applications, while C# is primarily used for developing applications on the Microsoft .NET platform.
Below are sample questions and answers covering key database and SQL concepts often asked in Cognizant interviews.
Normalization is the process of structuring the data in a relational database in such a way as to minimize duplication and to increase the consistency of data. It means splitting the big tables into smaller tables that have a relationship with each other and setting up the relations between them. Normalization is very helpful in making database access and management less time-consuming.
Database languages are split into different categories:
Structured Query Language (SQL) is a standard programming language used to manage and manipulate relational databases. SQL is essential for querying data, updating records, managing database objects, and controlling database access.
An index is a database object that improves the speed of data retrieval operations on a table. It works like an index in a book, allowing the database to find rows more quickly without scanning every record.
A database transaction is a sequence of operations performed as a single logical unit of work. The main properties are known as ACID:
DCL is used to control access to data in a database. Common DCL commands include GRANT (to give user access privileges) and REVOKE (to remove access privileges).
TCL manages the changes made by DML statements and controls the processing of transactions in a database. Common TCL commands are:
Database objects are the components that represent or hold data in the database. Some examples are tables, views, indexes, sequences, triggers, and stored procedures.
Relational databases organize data in tables that have relationships with each other, making it more manageable, retrievable, and resistant to inconsistencies. They are the backbone of most modern applications because of their stability and ability to handle complex queries.
Cognizant recognizes that candidates from non-IT backgrounds bring valuable perspectives and foundational knowledge. Technical questions for these candidates focus on essential concepts and practical applications relevant to their educational experience, rather than advanced programming.
DBMS stands for Database Management System. It is software that manages, organizes, and facilitates access to databases. DBMS is important because it ensures data consistency, security, and efficient data handling.
Normalization is the process of structuring a database to minimize redundancy and improve data integrity. It involves dividing large tables into smaller, related tables and defining relationships among them.
Data types define the kind of data a variable can hold, such as integers, floats, or characters. They help programming languages properly allocate memory and perform accurate operations on data.
Arrays are fixed-size collections of elements of the same data type, stored in contiguous memory locations. Lists are dynamic collections that can grow or shrink in size, and may allow elements of different data types depending on the programming language.
OOPs stands for Object-Oriented Programming. It is a programming paradigm based on objects and classes, emphasizing encapsulation, inheritance, and polymorphism for better code organization and reusability.
An operating system is system software that manages the computer hardware and software resources, providing services and an interface for user applications.
Python is a high-level, easy-to-learn programming language known for its readability. Python basics include understanding data types, lists, arrays, and simple control structures like loops and conditionals.
Data structures are ways to organize and store data efficiently (e.g., arrays, lists). Algorithms are step-by-step procedures or formulas for solving problems, essential for effective programming and problem-solving.
Networking refers to connecting computers and devices to share resources and data. It involves understanding protocols, hardware, and software that enable communication between devices.
Understanding basic programming language concepts helps non-IT candidates solve problems, automate tasks, and communicate more effectively with technical teams, making them versatile contributors in any role.
Bottom Line: Non-IT candidates who demonstrate logical reasoning and curiosity stand out as fast learners adaptable to technology roles.
