Answer:
#include <stdio.h>
int fib(int n) {
if (n <= 0) {
return 0;
}
if (n <= 2) {
return 1;
}
return fib(n-1) + fib(n-2);
}
int main(void) {
for(int nr=0; nr<=20; nr++)
printf("Fibonacci %d is %d\n", nr, fib(nr) );
return 0;
}
Explanation:
The code is a literal translation of the definition using a recursive function.
The recursive function is not per se a very efficient one.
Answer:
200 nm
Explanation:
We need a constructive interference to see the bright reflection
we know that
where m=1 and
is the wavelength of the gasoline
so 
putting the value of m and
in thickness equation

so the thickness of the film will be 200 nm

Answer:
The number of invoices for each vendor that have a larger balance due than the average balance due for all invoices.
Explanation:
This part of the code below
WHERE InvoiceTotal - PaymentTotal - CreditTotal >
(SELECT AVG (InvoiceTotal - PaymentTotal- CreditTotal)
FROM Invoices)
gives the condition to pick the invoices with balance that are greater than the average balance for all invoice.
This part of the code below
GROUP BY VendorName
ORDER BY BalanceDue DESC;
then enables the program to group the result of the above condition by VendorName and sort the resulting rows in the order of BalanceDue. You will therefore, obtain for each row in the NumberOfInvoices column, the number of invoices for each vendor that have a larger balance due than the average balance due for all invoices.
