The declaration could be done multiple times either of a variable or of function.
Variable or function could be defined only once.

Declaration of variable mean to tell compiler their is a varfunctstruct of particular data type. Definition of variable mean asking compiler to allocate memory to variable or define storage for that variable. you can define a variable only one time but you can declare it as many time you want.
