Thus the third value is 1+1=2, the fourth is 1+2=3, the fifth is 2+3=5, etc. Thus, the sequence is 1, 1, 2, 3, 5, 8, 13, 21, …. Write a code fragment using c++ that obtains a positive integer n from the user and displays the sum of the first n numbers in the Fibonacci sequence. If n is not positive, use cout to print out an error message. Put this code fragment in your main() of your project.
