Shifting a bit to the left in binary representation multiplies the number by 2, effectively doubling its value.
Bitwise Operation: A left shift operation (<<) moves all bits in a binary number to the left by a specified number of positions.
Doubling Effect: For example, shifting the binary number 0001 (1 in decimal) to the left by 1 results in 0010 (2 in decimal).
Zero Fill: New bits introduced on the right are...
A pointer is a variable that stores the memory address of another variable, enabling direct memory access and manipulation.
Pointers are used in languages like C and C++ to manage memory efficiently.
Example: int *ptr; // ptr is a pointer to an integer.
Pointers can be dereferenced to access the value at the memory address they point to.
Example: *ptr = 10; // assigns 10 to the integer variable pointed by ptr.
Pointers...
Accessing a memory location directly involves using pointers in programming languages like C or C++.
Use pointer variables to store the memory address of the location you want to access
Dereference the pointer to access the value stored at that memory location
Example: int *ptr; ptr = &variable; value = *ptr;

Swapping two numbers without using a third variable in C code.
Use bitwise XOR operation to swap two numbers without using a third variable.
Example: int a = 5, b = 10; a = a ^ b; b = a ^ b; a = a ^ b; // Now a = 10, b = 5

Explain the expected output or outcome of the code
Design patterns in C++ are reusable solutions to common problems in software design.
Design patterns help in creating flexible, maintainable, and scalable code.
Examples of design patterns in C++ include Singleton, Factory, Observer, and Strategy.
Each design pattern has its own purpose and can be applied in different scenarios.
Understanding design patterns can improve code quality and efficiency.
Constructors are special methods in a class that initialize objects when they are created.
Constructors have the same name as the class they belong to.
They do not have a return type, not even void.
A class can have multiple constructors (constructor overloading).
Example: In Java, 'public ClassName()' is a default constructor.
Constructors can take parameters to initialize object attributes.

Plan vs Actual refers to the comparison between projected outcomes and actual results in production management.
Performance Measurement: Regularly compare planned production output with actual output to identify discrepancies.
Root Cause Analysis: If actual output falls short, conduct a root cause analysis to determine underlying issues, such as equipment failure or labor shortages.
Adjusting Plans: Use insights from actu...

Polymorphism is the ability of a single function or method to operate on different types of data.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).
Example: Inheritance in object-oriented programming languages like Java allows for polymorphism.
Example: A method that takes ...
ADAS stands for Advanced Driver Assistance Systems. It refers to technologies that assist drivers in the driving process.
ADAS includes features like adaptive cruise control, lane departure warning, and automatic emergency braking.
These systems use sensors and cameras to monitor the vehicle's surroundings and provide alerts or assistance to the driver.
ADAS aims to improve safety, reduce accidents, and enhance the overal...
