Questions related to c++ concepts like templates, copy constructor and inheritance. Questions related to pointers.

Q1. What is inheritance and types of inheritance
Ans. 
Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.
• Inheritance allows code reuse and promotes code organization.

• There are different types of inheritance: single, multiple, multilevel, hierarchical, and hybrid.

• Single inheritance involves a class inheriting from a single base class.

• Multiple inheritance involves a class inheriting from multiple base c...read more

Q4. What are constructors and destrutors.
Ans. 
Constructors and destructors are special member functions in object-oriented programming languages.
• Constructors are used to initialize the object's data members when it is created.

• Destructors are used to free up any resources allocated by the object when it is destroyed.

• Constructors have the same name as the class and no return type.

• Destructors have the same name as the class preceded by a tilde (~) and no return type.

Q5. What is copy constructor and how is it different from regular constructors?
Ans. 
Copy constructor creates a new object by copying an existing object of the same class.
• Copy constructor is used to create a new object with the same values as an existing object.

• It takes an object of the same class as a parameter.

• It is different from regular constructors as it creates a new object by copying an existing object.

• Copy constructor is invoked when an object is passed by value or returned by value.

Q2. What is virtual function, abstract class, differences between virtual function and pure virtual function
Ans. 
Virtual functions allow polymorphism, abstract classes cannot be instantiated, pure virtual functions have no implementation.
• Virtual functions are functions in a base class that can be overridden in derived classes

• Abstract classes are classes that have at least one pure virtual function and cannot be instantiated

• Pure virtual functions have no implementation and must be overridden in derived classes

• Virtual functions can...read more

Q3. Difference between copy constructor and = operator.
Ans. 
Copy constructor creates a new object by copying an existing object, while = operator assigns the value of one object to another.
• Copy constructor is used to create a new object with the same values as an existing object.

• = operator is used to assign the value of one object to another.

• Copy constructor is invoked when a new object is created from an existing object.

• = operator is invoked when an existing object is assigned...read more

Q4. What are lambda functions.
Ans. 
Lambda functions are anonymous functions that can be passed as arguments or stored in variables.
• Lambda functions are also known as anonymous functions or closures.

• They are commonly used in functional programming languages like Python and JavaScript.

• Lambda functions can be used to create higher-order functions, which take other functions as arguments.

• They are often used for filtering, mapping, and reducing data in colle...read more

Q1. What is endianness and wrote c program for endianness
Ans. 
Endianness refers to the order in which bytes are stored in memory. There are two types: big-endian and little-endian.
• Big-endian systems store the most significant byte first, while little-endian systems store the least significant byte first.

• Endianness can affect how data is interpreted and manipulated in a computer system.

• Example: In a big-endian system, the number 0x12345678 would be stored as 12 34 56 78 in memory.
