Lining up columns nicely.


Posted on 16th Feb 2014 07:03 pm by admin

Hello everyone, I'm having problems with making columns line up properly. Here is my code:




1

8
9
10
11
12
13
14
15
16

#include #include using namespace std; int main () { double price = 1; //stores the starting price double yearInt = 1; //stores the yearly interest double monthInt; //will store monthly interest once yearly interest is added double payment = 1; //stores how much is paid per month double month = 1; //month counter double paidInt; //displays how much interest was paid double paidPrice; //displays how much of loan was paid off after interest double balance ; //displays balance after payment is made double remBalance; { cout << "Please enter the dollar amount of the loan: $"; cin >> price; cout << "Please enter the yearly rate of interest: "; cin >> yearInt; cout << "Please enter the monthly payment made: $"; cin >> payment; cout << "Month Principle Interest Paid Principle Paid Remaining Balance" < 0) { month++; paidInt = balance * monthInt; paidPrice = payment - paidInt; remBalance = balance - paidPrice; cout << month << setw(6) << " "<< balance << setw(6)<< " "<< paidInt << setw(6) << " "<< paidPrice << setw(6) << " "<< remBalance << endl; balance = remBalance; } cout << "Number of months to pay off loan: " << month << endl; cout << "Total interest paid on loan: " << endl; cout << "You have a credit of: " << remBalance << endl; } }



At the moment I'm using the setw manipulator. When the program prints, it looks like this:



Please enter the dollar amount of the loan: $400 Please enter the yearly rate of interest: 20 Please enter the monthly payment made: $20 Month Principle Interest Paid Principle Paid Remaining Balance 2.00 400.00 6.67 13.33 386.67 3.00 386.67 6.44 13.56 373.11 4.00 373.11 6.22 13.78 359.33 5.00 359.33 5.99 14.01 345.32 6.00 345.32 5.76 14.24 331.07 7.00 331.07 5.52 14.48 316.59 8.00 316.59 5.28 14.72 301.87 9.00 301.87 5.03 14.97 286.90 10.00 286.90 4.78 15.22 271.68 11.00 271.68 4.53 15.47 256.21 12.00 256.21 4.27 15.73 240.48 13.00 240.48 4.01 15.99 224.49 14.00 224.49 3.74 16.26 208.23 15.00 208.23 3.47 16.53 191.70 16.00 191.70 3.19 16.81 174.89 17.00 174.89 2.91 17.09 157.81 18.00 157.81 2.63 17.37 140.44 19.00 140.44 2.34 17.66 122.78 20.00 122.78 2.05 17.95 104.83 21.00 104.83 1.75 18.25 86.57 22.00 86.57 1.44 18.56 68.02 23.00 68.02 1.13 18.87 49.15 24.00 49.15 0.82 19.18 29.97 25.00 29.97 0.50 19.50 10.47 26.00 10.47 0.17 19.83 -9.36 Number of months to pay off loan: 26.00 Total interest paid on loan: You have a credit of: -9.36 Press any key to continue . . .

I am aware I can just change setw to a higher number to make it look nicer, but I want to do more than that. If you look at where the 10th month is, the whole line is indented a little bit and doesnt line up properly with the above lines. I am also concerned that if the user enters numbers with more digits, the output won't line up properly either.

How can I make it so that everything will line up nicely, no matter what (within reason) the user enters?

Thanks a lot for any help.
