Recursion Example

    void main()

{

    static int i=5;

    if(--i){

         main();

         printf("%d ",i);

    }

}

Answer:

 0 0 0 0

Explanation:

    The variable "I" is declared as static, hence memory for I will be allocated for only once, as it encounters the statement. The function main() will be called recursively unless I becomes equal to 0, and since main() is recursively called, so the value of static I ie., 0 will be printed every time the control is returned.
