Thread: Problems

Hey guys, if anyone can help I'd greatly appreciate it. I have this homework problem that doesn't seem to wanna work with me.
"you have bought a car, taking out a loan with annual interest rate of 9%. You will make 36 monthly payments of $165.25 each. You want to keep track of the remaining balance you owe after each monthly payment. The formula for the remaining balance is:

Bal k= pmt[1-(1+i)^(k-n)]/i

Bal k = balance remaining after kth payment
k= payment number (1,2,3...)
pmt= amount of monthly payment
i= interest rate per month (annual rate /12)
n= total number of payments to be made.

If you're still reading this ..here is the source code I've gotten so far... Please Help

#include<iomanip.h>
#include<math.h>

main()
{ _asm finit;
int K, N;
float Pmt=165.25, I=.09, Bal;

for (N=1;N<=36;N++){
cout<<"\nPayment Number: "<<N<<endl;

Bal = Pmt* (1- pow((1+(I/12)),N-K))/(I/12);

cout.setf(ios::floatfield, ios::showpoint);
cout.setf(ios::fixed) ;
cout<<setprecision(2) ;

cout<<"Monthly Payment is: $" <<Pmt<<endl; cout<<"Monthly Interest Rate is: " <<I<<endl ;
cout<<"Total Number of Payments is: "<<N<<endl ;
cout<<"Balance is : $" <<Bal<<endl;

}//for loop

return 0;
}//main

Here, I fixed up your code.

Mainly, you had the variables N and K doing each other's job. So I just switched those and did some other housekeeping. I believe that this is what you wanted:

Code:

#include<iomanip.h> 
#include<math.h> 

main() 
{ 
   _asm finit;
	
   int K,  N = 36; 
   double Pmt = 165.25, I=0.09, Bal; 

   for (K = 1; K <= 36; K++)
   { 
    cout << endl <<"Payment Number: "<< K << endl; 

    Bal = Pmt * ( 1 - pow((1 + I/12),(K - N)) ) / (I/12);  //Bal k= pmt[1-(1+i)^(k-n)]/i  

     cout.setf(ios::floatfield, ios::showpoint); 
     cout.setf(ios::fixed) ; 

		
    cout << setprecision(2)
         << "Monthly Payment is: $" << Pmt <<endl
         << "Monthly Interest Rate is: " << I/12 <<endl 
         << "Total Number of Payments is: "<< N <<endl  
         << "Balance is: $" << Bal <<endl; 

   }

return 0; 
}

Good luck

Hey thanks a lot bro..I appreciate it big time!
