Difference between fn overriding and fn overloading?

overloading Used in same class, overriding occurs in inheritance

What is function overloading?

multiple functions with Same name, different signatures

Which statement is true about constructors?

Multiple constructors allowed in a class

What happens when a destructor is defined as virtual?

Ensures proper cleanup in inheritance

Purpose of template functions in C++?

write functions that can Work with any data type

What if a class has no destructor?

compiler Generates default destructor

What is the key difference between structure and class?

must be Defined inside a class
Cannot be overridden
must be Defined outside the class
Allow runtime polymorphism
2
Difference between fn overriding and fn overloading?
overloading works Only for member functions
overloading Used in same class, overriding occurs in inheritance
overriding Changes return type
overloading Requires 'virtual' keyword
3

Multiple Inheritance
Hierarchical Inheritance
Single Inheritance
Multilevel Inheritance
4
How does exception handling improve reliability?
Prevents syntax errors
Handles runtime errors
Removes need for debugging
Makes program faster
5
What is function overloading?
Using function multiple times
Multiple functions in single statement
multiple functions with Same name, different signatures
Function inside another function
6
Which statement is true about constructors?
Must take parameters
Multiple constructors allowed in a class
Can return values
Cannot be overloaded
7
What happens when a destructor is defined as virtual?
Ensures proper cleanup in inheritance
Cannot be overloaded
Cannot be called explicitly
Cannot be inherited
8
Purpose of template functions in C++?
Define functions inside class
Create multiple instances
Enforce type safety
write functions that can Work with any data type
9
What if a class has no destructor?
Program Will not compile
compiler Generates default destructor
Cannot be instantiated
Object cannot be destroyed
10
What is the key difference between structure and class?
Structures have only public members
By default, members of a class are private, mem. of a structure are public
Structures cannot have member functions
Classes support inheritance while structures do not
