Use C++ 1 a)Write a console program which creates an array of size 100 integers. Then use Fibonacci function Fib(n) to fill up the array with Fib(n) for n = 3 to n = 103: So this means the array looks like: { Fib(3), Fib(4), Fib(5), ...., Fib[102) }. For this part of assignment you should first write a recursive Fib(n) funcion, as was done in class.For testing, print out the 100 integers. 1 b) For second part of this...
