Answer 1

 #include <iostream>

int main() {
	int base_price[] = { 100, 130, 150, 160, 165 };
	int num;
	double price;
	std::cout << "Enter the number of subjects in the portrait: ";
	std::cin >> num;
	if (num > 5)
		num = 5;
	price = base_price[num - 1];
	
	char ch;
	std::cout << "Do you want a fancy background (y/n)? ";
	std::cin >> ch;
	if (ch == 'y')
		price += base_price[num - 1] * 0.1;
	
	std::cout << "Do you want an appointment date (y/n)? ";
	std::cin >> ch;
	if (ch == 'y')
		price += base_price[num - 1] * 0.1;

	std::cout << "The price is: $" << price << std::endl;
	return 0;
