Consider the following recursive function. What does it calculate in terms of x, y, and z?  01: Private Function CalcRecurse(ByVal x As Integer, ByVal y As Integer, ByVal z As Integer) As Integer 02: If x <= 1 Then 'Assume that CalcRecurse always starts with x > 1 03: Return y 04: Else 05: Return z + CalcRecurse(x - 1, y, z) 06: End If 07: End Function

Question 3The program below reads two integers. Then a function with the followingprototype is called:                              void div_rem(int a, int b, int *divides, int *remains); This function is passed the two integers. It divides them (using integer division),and writes the answer over wherever “divides” points. Then it finds theremainder and writes it into where “remains” points. Thus for 20 and 3, 20divided by 3 is 6, remainder 2. Implement the div_rem function.  #include <stdio.h>void div_rem(int a, int b, int *divides, int *remains);  int  main(void)  {                int a, b;                 int div = 0;               int rem = 0; printf("enter two integers ");scanf("%i %i", &a, &b); div_rem(a, b, &div, &rem);  printf("%i divided by %i = %i "             "remainder %i\n", a, b, div, rem);  return 0;}
