This program is supposed to create the complete amortization table for a loan given a payment amount, interest rate and number of payments to make. The formula used to calculate this comes out correct when I do it by hand but when I run the program, it gives me the same balance over and over again until the number of payments runs out. I think the problem lies in the incrementing of "e" to go back into the formula.
#include %26lt;iostream%26gt;
#include %26lt;cmath%26gt;
using namespace std;
int main ()
{
double a, b, c, d, e, bm, y;
cout %26lt;%26lt; "Enter payment amount:" %26lt;%26lt; flush;
cin %26gt;%26gt; a;
cout %26lt;%26lt; "Enter interest rate (9% as 0.09):" %26lt;%26lt; flush;
cin %26gt;%26gt; b;
cout %26lt;%26lt; "Enter number of payments:" %26lt;%26lt; flush;
cin %26gt;%26gt; c;
bm = b/12;
y = pow (( 1 + bm ), (e - c));
d = a * (1 - y) / bm;
for (e = 1; e %26lt;= c; e++)
cout %26lt;%26lt; "After payment #" %26lt;%26lt; e %26lt;%26lt; " the balance on the loan is $" %26lt;%26lt; d %26lt;%26lt; endl;
return 0;
}
C++ increment question?
you need the equations inside the for loop.
try it like this:
for (e = 1; e %26lt;= c; e++)
bm = b/12;
y = pow (( 1 + bm ), (e - c));
d = a * (1 - y) / bm;
cout %26lt;%26lt; "After payment #" %26lt;%26lt; e %26lt;%26lt; " the balance on the loan is $" %26lt;%26lt; d %26lt;%26lt; endl;
}
Reply:you are not changing d in the for loop, so it prints the same amount always
