Hi, I am working on a program for a school assignment. I am not sure exactly how to code this at all. If anyone could help, that would be very much appreciated. This is the problem:


Write a C++ program that compares the execution time of the above summation using two different solutions: one that uses loops, and another that uses the closed form approach. Use large values of n for the comparisons, such as, 10^7, 10^8, 10^9, 10^10, 10^11,10^12, 10^13, and 10^14. Provide a comparison table for the execution time in both solutions.Do not worry about the value of the actual sum. Overflow will occur in the sum value rendering it invalid; however, this is not the primary concern of the program. Execution time is the primary concern.

Thank you for your help
