To swap values of two variables without a third variable, use arithmetic operations.
Use addition and subtraction to swap values
Example: a = 5, b = 10. a = a + b (a = 15), b = a - b (b = 5), a = a - b (a = 10)
Object-oriented programming paradigm focusing on objects and classes for code organization and reusability.
Encapsulation: bundling data and methods that operate on the data into a single unit (class)
Inheritance: ability of a class to inherit properties and behavior from another class
Polymorphism: ability to present the same interface for different data types
Abstraction: hiding the complex implementation details an...
Exception handling is the process of responding to unexpected events or errors in a program.
Exception handling allows developers to gracefully handle errors and prevent crashes in a program.
It involves using try, catch, and finally blocks to handle exceptions.
Examples include catching a divide by zero error or a file not found exception.
Code to generate Fibonacci sequence
Use a loop to generate Fibonacci numbers
Start with 0 and 1 as the first two numbers
Add the previous two numbers to get the next number
Repeat until desired number of Fibonacci numbers are generated
What people are saying about TCS
Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones.
Create an array to store the Fibonacci sequence
Use a loop to calculate each number in the sequence by adding the previous two numbers
Start with 0 and 1 as the first two numbers in the sequence
OOPs concept is a programming paradigm based on the concept of objects, which can contain data in the form of fields and code in the form of procedures.
OOPs stands for Object-Oriented Programming
Key concepts include encapsulation, inheritance, and polymorphism
Example: Inheritance - a class 'Animal' can be inherited by classes like 'Dog' and 'Cat'
Inheritance allows classes to inherit properties and methods from other classes, while abstraction hides complex implementation details.
Inheritance promotes code reusability. Example: A 'Dog' class can inherit from an 'Animal' class.
Abstraction simplifies complex systems by exposing only necessary parts. Example: An abstract class 'Shape' with a method 'draw()'.
Inheritance can be single or multiple. Example: In Ja...
Null indicator is a flag used to indicate whether a value is null or not in database systems.
Null indicator is used in database systems to handle null values efficiently.
It is typically a single bit flag associated with a data field.
A null indicator value of 0 indicates that the corresponding value is not null, while a value of 1 indicates it is null.
The cond parameter is a conditional parameter used in programming to evaluate a series of conditions and return a value based on the first condition that is true.
Cond parameter is commonly used in programming languages like Lisp and Clojure.
It takes a series of pairs where the first element is a condition and the second element is the value to return if the condition is true.
Example: (cond ((= x 0) 'zero) ((= x 1)...
Procedures are a set of instructions or steps to be followed in order to complete a task or achieve a goal.
Procedures help in organizing tasks and ensuring consistency in execution.
They can be written in a formal document or informally communicated.
Examples include cooking recipes, assembly instructions, and software development processes.
