Hi,

Could you please help me to solve the question. Also, could you please answer questions in clear hand-writing and show me the full process, thank you (Sometimes I get the answer which was difficult to read).Thanks a lot.

Determine a formula for how many gifts would need to be distributed in the song The N days of Christmas. You know that means you need to determine a closed formula (one without any sigmas) which depends on N, where N is the number of days of gift-giving.

Total gifts = = ------------------------- = ---------------------------

To verify your formula, you should write a program (in the language C++), which takes an input N and calculates Total Gifts two ways: (1) using your formula and (2) using a counter with loop(s).

Note that PNC Bank has a website where they analyze the cost of the presents: http://www.pncchristmaspriceindex.com/
