Function overloading vs function overriding

function overloading:

is happened when we call a function and give it a parameters more than the parameters that it takes, ex: a function x has 1 parameter of type int, if we call it and give it 2 parameters then its overloading, also if we call it and give it 1 parameter of a data type not int then its also an overloading.

Function overriding:

Its when we rewrite the function in the sub class.
