The International Conference on Mathematical Sciences and Technology, Math Tech, is a biennial conference organised by the School of Mathematical Sciences, USM. This event is open to all national and international experts, practitioners, researchers, and academics to gather and share their knowledge. The details of fees for participation in the conference are shown in the following table. Category Local (RM) International (USD) Presenter 990 260 Observer 600 150 Note: 1 USD = RM4.20 Assignment Requirement Part 1: Create Invoice Construct a C++ program to do the following tasks: a. Enter the participant's name, category, nationality, accommodation (Yes/No). b. If the answer for the question on accommodation is Yes, the program will ask for the number of days. Then the program will call function calcAccommodation() to calculate the accommodation charges. calcAccommodation() receives accommodation (Yes/No), number of days and participation type (local/international) as parameters and return the accommodation charge to the main program. The price per night per person is RM150 for local participant, and USD 100 for international participant. c. Call the calcFee() function which receives participant category and type as parameters, calculate the fees, and return it via reference parameter. d. Calculate the total fees and accommodation charges and store the result to variable totalCharge. e. Call function printInvoice() to print the invoice. Sample invoice is given as follows: International Conference on Mathematical Sciences and Technology (MathTech) : 20 January 2022 : 0001 : Muhammad Irfan Ali : Presenter Invoice Date Invoice No Name Category Accommodation (Y/N) : Y : 990.00 : 300.00 : 1290.00 Conference Fee Accommodation Fee Total Amount Due (RM) Terms & Conditions Payment is due within 30 days.
