A recursive power program is given below.
int powa(int x, int n) {
if (n=1) {
return x;
} else {
return x * powa(x, n - 1):
void main) {
int val;
val = pow(2,3);
The contents of stack before the call of pow(2,3) in main and after 1 recursive call is given below:
ARI for main

First ARI for
Functional value
Parameter x
Parameter n
Dynamic link
Static link
Retun (to main)

ARI for main
a) Show the contents of the stack after each recursive call until you reach the base case.
b) Show the contents of the stack after each retum until you reach back to the main function.
