Constructor is a special member function used for initializing objects. Virtual constructor is not possible in C++. Virtual destructor can be implemented.
Constructor is a special member function with the same name as the class, used for initializing objects.
Virtual constructor is not possible in C++ as constructors cannot be virtual.

Understanding getter setter, virtual function, encapsulation, abstraction in OOP
Getter and setter methods are used to access and modify private class members respectively
Virtual functions in C++ allow dynamic binding and are overridden in derived classes
Encapsulation is bundling data and methods that operate on the data together
Abstraction is hiding the complex implementation details and showing only necessary features

Friend function is a function that is not a member of a class but has access to its private and protected members. Getter setter are methods used to access and modify private variables. Static variables are shared among all instances of a class. Static functions are functions that can be called without an instance of the class.
Friend function allows external functions to access private and protected members of a class.

Diamond problem occurs in multiple inheritance when a class inherits from two classes that have a common base class.
Diamond problem can be resolved using virtual inheritance in C++.
Virtual inheritance ensures that only one instance of the common base class is inherited.
Example: class A is inherited by classes B and C, then class D inherits from both B and C. Using virtual inheritance for B and C in D resolves the diamo

The volatile keyword in programming is used to indicate that a variable's value can be changed unexpectedly.
Used to prevent compiler optimizations that assume variable values do not change outside of the program
Commonly used for variables that are modified by hardware or other threads
Example: volatile int sensorValue; // variable updated by external sensor
Unions in C are used to store different data types in the same memory location.
Unions are used to save memory by allowing different data types to share the same memory location.
They are commonly used in situations where only one of the data types needs to be accessed at a time.
For example, a union can be used to store an integer and a float, with only one being accessed depending on the context.
A 120-ohm resistor is used in the CAN protocol to match the characteristic impedance of the network and reduce signal reflections.
The 120-ohm resistor helps to match the characteristic impedance of the CAN network, which is typically 120 ohms.
It reduces signal reflections that can cause data corruption and communication errors.
The resistor is placed at both ends of the CAN bus to ensure proper termination.
Without the r...
PWM is a technique used to encode analog signal using digital pulses of varying widths.
PWM is commonly used in controlling the speed of motors, brightness of LEDs, and audio signals.
It works by varying the width of the pulse in a fixed time period, known as the duty cycle.
The average voltage of the signal is determined by the duty cycle - higher duty cycle means higher average voltage.
PWM is achieved by rapidly switchi...
