#print
Print the 20 Fibonacci numbers beginning with 2
(the sequence is 2,3,5,8,... where each number
is the sum of the immediately preceding pair of numbers.
Start with the pair 1,1).
Print each number on a separate line as a five digit
number (remember %3d in printf? %5d does five digits).
Compile and test your program; then type "ready".
