C recursion function

Recursion Concept :

  1. Recursion is basic concept in Programming.
  2. When Function is defined in terms of itself then it is called as “Recursion Function“.
  3. Recursive function is a function which contains a call to itself.
int factorial(int n)
{
 if(n==0)
    return(1);
 else
    return( n * factorial(n-1));
}


Warning of using recursive function in C Programming : 

    

  1. Recursive function must have at least one terminating condition that can be satisfied.
    2. 

  2.  Otherwise, the recursive function will call itself repeatably until the run time stack overflows.
    3.
