Question

c++ help with get.line

Answer 1

#include <iostream>;
#include <iomanip>;
#include <string>
#include <cmath>
using namespace std;

int main()
{
int yearRate, numbPay;
double loan, monthPay, paidBack, interest, rate;

cout << setprecision(2) << fixed;
//gets loan amount,
cout << "Enter the loan amount => ";
cin >> loan;
//gets yearly interest rate
cout <<"Enter the yearly interest rate as a percentage => ";
cin >> yearRate;
//gets number of payments
cout << "Enter the number of payments ";
cin >> numbPay;



//calculates Monthly Payment, Amount Paid back, and Interest Paid
rate = yearRate / 1200.0;
monthPay = (( rate * pow((1+rate),numbPay)) / ( pow((1+rate),numbPay) - 1 ) ) * loan;
paidBack = monthPay * numbPay;
interest = paidBack - loan;

//outputs the loan, yearRate, numbPay, monthPay, paidBack, and interest variables
cout << "Loan Amount: $ " << loan;
cout << "\nYearly Interest Rate: " << yearRate << "%";
cout << "\nNumber of Payments: " << numbPay;
cout << "\nMonthly Payment: $ " << monthPay;
cout << "\nAmount Paid Back: $ " << paidBack;
cout << "\nInterest Rate: $ " << interest;

//option to end program
cin.ignore();
cout << "\nPress enter to end";
cin.get();
return 0;
}

Answer 2

the get.line()works fine and pauses the program until i press enter just fine, unless i use numbers with decimals for the prompts.

Answer 3

This sounds like a bug, but then again, I'm only learning C++ now myself. I tried the code in Codeblocks and if I enter a number with decimals for rate then it won't even let me enter the number of payments.
