overloading refers to -same name but different definitions and parmeters. 
Overriding refers to --'replacement' of methods.

In overloading you are extending the definition . 
ie if you over load a operator " + " whith a object then  
them + can be used to perform the basic additoin and defintion given at the time of operator overload . 
 
The overriding which used in Inheretence . ie if you want to change the definition .

Function Overloading is the implementation of static polymorphism where same function name having different defenitions for different uses. 
 
Function overriding is applicable for dynamic polymorphism where where the function name and the definition are same but the function call is decided at the run time according to the type of object reference.

type of arg.

overriding:

overloading is mainly for operators and overriding is for functions

Overloading is related to the use of a function or an operator. For example you can use a function for adding some integers as well as floats so this function is overloaded as it works for two different kind of inputs.

Where as overiding is in the case of classes in the object oriented programming or modeling. In this perspective you make a new class interacting with an existing one by implementing some new or restricted feature. For example you click to draw a shape from the menu but in the view class and further in every class (line, rectangle, triangle and circle etc) there exists a specific draw function.

Additionally:

Overloading is done in same scope (i.e. having two functions with same name (but different signature in same class scope or same file scope).
While
Overriding is specifically related to inheriting & inherited classes, i.e. inheriting (derived) class MAY override a function, which was already defined in inherited (base) class.

Overloading functions: will have different signature (i.e. argument list is different by No of Args OR Type of Args OR Order o Args)
While
Overriding Functions: will have same signature.

Overloading functions are resolved during compile time
while
Overriding functions are resolved during runtime.
