What is the difference between function overloading and function overriding ? Explain.

Answer 1

Override:
In hierarchy context happen when you redefine a inherited method without change his signature (return type and arguments)

Overload:
This happen when you define a function/method with differents arguments (count or/and types) using a yet defined name in visible scope

Answer 2

Old answer to a similar question:

And overloading implements the same function name with different behaviour depending on the passed parameters.

int foo(int a){
return a+5;
}

float foo(float a){
return a+0.5;
}

It uses the implementation which fits your passed arguments.

foo(5) will run the int version
foo(0.5) will run the float version
