Answer 1

#include<iostream>

#include<sstream>

double enter_number (std::string& prompt)

{

double result {};

std::string input {};

while (1)

{

std::cout << prompt;

std::cin >> input;

std:stringstream ss;

ss << input;

if (ss >> result)

break;

std::cerr << "Invalid input: " << input << std::endl;

}

return result;

}

int main()

{

double amount, tax_rate, tax, total, ;

amount = enter_number ("Enter amount ($): ");

tax_rate = enter_number ("Enter tax rate (%): ");

tax = amount * tax_rate;

total = amount + tax;

std::cout << "Tax ($): " << tax << std::endl;

std::cout << "Total ($): " << total << std::endl;

}
