Best Answer

A recursive function is one that calls upon itself until a given result in the original call is met.

Take a look at this example.

Program Recursion;

Uses

crt;

Var

number:longint;

Function Factorial(number:longint):longint;

Begin

if number > 0 then

factorial:=number*factorial(number-1)

else

factorial:=1;

End;

Begin

clrscr;

readln(number);

writeln(factorial(number));

readln;

End.

Note how the function factorial calls itself.

A recursive function does have an element of repetition.

However, it should never repeat its actions verbatim - or this would create an infinite recursion.

A recursive function has one or more base cases - where the function simply returns a value.

A recursive function also has one or more recursive cases- where the function calls itself with a different ("smaller") input, and may combine the results of these calls.

What is the difference between function and recursive function?

I will explain in the easiest way the difference between the function and recursive function in C language. Simple Answer is argument of the function is differ but in the recursive function it is same:) Explanation: Function int function(int,int)// function declaration main() { int n; ...... ...... n=function(a,b); } int function(int c,int d) { ...... ...... ...... } recursive Function: int recursive(int,int)// recursive Function declaration main() { int n; ..... ..... ..... ..... n=recursive(a,b); } int recursive(int a,int b) { ..... .... .... .... } Carefully see, In the recursive Function the function arguments are same.


Is macro a recursive function?

If you're asking if the c preprocessor supports recursive macros, the answer is no. The preprocessor is single-pass and since the "function" must be defined before it can be referenced, it can not be recursive.

A function can map for sets with infinite elements. Recursive variables, being 'algorithms of algorithms', are restricted to finite elements.

The efficiency of using recursive function rather than using ordinary function?

For some algorithms recursive functions are faster, and there are some problems that can only be solved through recursive means as iterative approaches are computationally infeasible.
