A LinkedList is a data structure that consists of a sequence of elements where each element points to the next element in the sequence.
Each element in a LinkedList is called a node and contains a value and a reference to the next node in the sequence.
LinkedLists can be singly linked (each node points to the next node) or doubly linked (each node points to both the next and previous nodes).
Inserting and deleting element...

Motors are rated in KW because they consume power, while transformers and generators are rated in KVA because they produce power.
Motors convert electrical energy into mechanical energy, so they consume power and are rated in KW.
Transformers and generators produce electrical energy, so they are rated in KVA based on their apparent power.
KVA takes into account both the real power (KW) and the reactive power (KVAR) produc...
The type of motor used in ceiling fans is an induction motor.
Ceiling fans typically use single-phase induction motors.
These motors are designed to provide a constant speed and are efficient in converting electrical energy into mechanical energy.
The motor consists of a stator and a rotor, with the stator being the stationary part and the rotor being the rotating part.
The stator contains windings that create a rotating m...
A thermal power plant generates electricity by converting heat energy into mechanical energy.
Thermal power plants use fossil fuels or nuclear energy to heat water and produce steam.
The steam drives a turbine, which is connected to a generator that produces electricity.
The heat source can be coal, natural gas, oil, or nuclear reactions.
The steam is condensed back into water and recycled in a closed-loop system.
Thermal p...
A program to generate a geometric progression (GP).
Take the first term, common ratio and number of terms as input.
Use a loop to calculate each term of the GP.
Print the generated GP as output.
A program to print factorial using recursion
Define a function to calculate factorial recursively
Base case: if the number is 0 or 1, return 1
Recursive case: multiply the number with factorial of (number - 1)
Print the factorial of a given number
Logic to reverse a string without using string functions
Iterate through the string from the last character to the first
Create a new string and append each character to it in reverse order
Polymorphism is the ability of an object to take on many forms. In C++, it is achieved through function overloading and virtual functions.
Polymorphism allows objects of different classes to be treated as objects of a common base class.
Function overloading enables multiple functions with the same name but different parameters.
Virtual functions allow derived classes to override base class functions.
