"WebA recursive definition of a function defines values of the function for some inputs in terms of the values of the same function for other (usually smaller) inputs. For example, the factorial function n! is defined by the rules. This definition is valid for each natural number n, because the recursion eventually reaches the base case of 0.

WebWhenever a function calls itself, creating a loop, then that's recursion. As with anything there are good uses and bad uses for recursion. The most simple example is tail recursion where the very last line of the function is a call to itself: int FloorByTen (int num) { if (num % 10 == 0) return num; else return FloorByTen (num-1); } WebA recursive function can also be defined for a geometric sequence, where the terms in the sequence have a common factor or common ratio between them. And it can be written as; an= r × an-1 Generally, the recursive function is defined in two parts. It a statement of the first term along with the formula/ rule related to the successive terms.
