C++ examples for Data Type:double
Calculate compound interest with a principal of $24.00 and
#include <cmath> #include <iomanip> #include <iostream> int main(int argc, const char *argv[]) { double amount; double principal = 24.0f; std::cout << std::fixed << std::setprecision(2); for (float rate = 0.05; rate <= 0.10; rate += 0.01) { std::cout << "\nInterest rate: " << rate * 100 << "%\n" << "Year" << std::setw(30) << "Amount on deposit" << std::endl; for (int year = 1626; year < 2020; year++) { amount = principal * pow(1.0 + rate, year - 1626); if (year == 2020) { std::cout << std::setw(4) << year << std::setw(30) << amount << std::endl; }/*from w w w . j a v a 2s .c o m*/ } } return 0; }
