What is the difference between Method Overloading and Method Overriding in C++?

Question

Do they use different signatures?

Answer 1

Inheritance: Overriding of functions occurs when one class is inherited from another class. Overloading can occur without inheritance.
Function Signature: Overloaded functions must differ in function signature ie either number of parameters or type of parameters should differ. In overriding, function signatures must be same.
Scope of functions: Overridden functions are in different scopes; whereas overloaded functions are in same scope.
Behavior of functions: Overriding is needed when derived class function has to do some added or different job than the base class function. Overloading is used to have same name functions which behave differently depending upon parameters passed to them.

Answer 2

hope u will understood about overloading and overriding

Answer 3

Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding means having two methods with the same method name and parameters (i.e., method signature).

Answer 4

Overloding means: the datatype or return type of overloaded function must be differ!
Overriding mean replacement!
If we have in parent class a function we want to replace that function or modify in child class that's called overriding!
The overriding function must be same!

Answer 5

Overloading a method (or function) in C++ is the ability for functions of the same name to be defined as long as these methods have different signatures (a different set of parameters). Method overriding is the ability of the inherited class rewriting the virtual method of the base class.

Answer 6

Aksita G Main Difference
Method overloading :- two or more function same name but different number of parameter like add(int a, int b, int c) , add(int a);
While
Method overriding :- Two or more function having same name and same paramenter's number but only the last one will get executed when it is called
Ex:
void add(){...}
void add(){.......}
add(); // it will call add{..........}
