New to Programming and Need Help
Hey Everyone this is my first post so I'll get the Intro's out of the way. I'm Kendra and I'm 21 years old and I'm a new Computer Programming Major. I'm halfway through my first semester as this major. I spent 2 years in College as a Nursing Major only to find out , after my Mothers death, that I do not want to be a Nurse lol I've always loved computers but everything that I know up to this point is self taught. I live in a small town and no one here does this kind of stuff so I'm somewhat on my own. I've been doing well in my classes (which are all ONLINE) but, C++ has been somewhat of a Pain in my Butt lol My other Programming classes are great.

SO, here is my problem. I'm having to create a program using While loops. The purpose of the program is to calculate monthly car payments for the user. I'm not allowed to use any Global Variables. I'm also not allowed to use functions so I have to use a Linear-straight-line program. My problem lies in the monPayment I keep getting this error.* error C2064: term does not evaluate to a function taking 1 arguments* I'm confused as to how I would get the monPayments to calculate correctly, given that the number of months (noMonths) has to be either 24, 36, 48 & 60.

My output should eventually look something like this;

Vehicle Price : 99999.99
Down Payment : 99999.99
_______________________
Loan Amount : 99999.99

Annual Interest Rate 99.99%

Monthly Payment Options
24 mo 99999.99
36 mo 99999.99
48 mo 99999.99
60 mo 99999.99

#include <iostream> //Access Cout
#include <cmath> //Access Power Functions
#include <iomanip> //Access Manipulators

using namespace std;

int main()

{
//Input Variables.

float price; //Price of vehicle
float downPayment; //Down Payment
float loanAmt; //Loan Amount (calculated)
float annualIntRate; //Annual Interest Rate (fraction)
float annualIntPercent; //Annual Interest Rate (percent)
float monIntRate; //Monthly Interest Rate (fraction)
int noMonths; //Number of MonthlyPayments
(24,36,48 & 60)
float monPayment; //Monthly Payment

//Prompt User for Input.

// Get Price.
cout << " Enter Price of Vehicle: ";
cin >> price;
// Get Interest Rate.
cout << " Enter Annual Interest Rate; ";
cin >> annualIntRate;
// Get Down Payment.
cout << " Enter Down Payment in dollars and cents: ";
cin >> downPayment;
cout << "Enter trade-in in dollars and cents: ";

// Calculations
// Formulas
//

while(price >= 50000.00);

{
loanAmt = price - tradeIn - downPayment;
monIntRate = annualIntRate / 12.0;
annualIntPercent = annualIntRate * 100.0;
loanAmt= price - downPayment - tradeIn;
monPayment=(loanAmt*monIntRate)(1.0 -(1 + monIntRate)-noMonth);

//Output results
cout << fixed << "Price of Vehicle: " << setprecision(2) << price << endl << "Trade in Value : " << setprecision(2) << tradeIn << endl
<< "Down Payment : " << setprecision(2) << downPayment << endl << "----------------------" << endl << "Loan Amount : " << setprecision(2) <<loanAmt <<endl << "Interest Rate : " << setprecision(2) << annualIntPercent << "%" << endl;

So rather than read that, and post something readable, your work-around hack was to remove all the closing braces and post an unreadable mess.

Not some hatchet job just to get past the code check filter designed to make life easier for the rest of us!

Sorry
Didn't mean to upset anyone. That was my very first post. My bad.

Code:

``` #include <iostream>                                //Access Cout #include <cmath>                                //Access Power Functions #include <iomanip>                                //Access Manipulators using namespace std; int main() {         //Input Variables.         float price;                                //Price of vehicle         float downPayment;                        //Down Payment         float tradeIn;                                //Trade in for vehicle         float loanAmt;                                //Loan Amount (calculated)         float annualIntRate;                //Annual Interest Rate (fraction)         float annualIntPercent;                //Annual Interest Rate (percent)         float monIntRate;                        //Monthly Interest Rate (fraction)         int noMonths;                                //Number of Monthly Payments (24,36,48 & 60)         float monPayment;                        //Monthly Payment         //Prompt User for Input.         // Get Price.         cout << " Enter Price of Vehicle: ";                 cin >> price;         // Get Interest Rate.         cout << " Enter Annual Interest Rate; ";                 cin >> annualIntRate;         // Get Down Payment.                 cout << " Enter Down Payment in dollars and cents: ";           cin >> downPayment;         // Get Trade In .                   cout << "Enter trade-in in dollars and cents: ";                   cin >> tradeIn;                                 // Calculations                         // Formulas                   //         while(price >= 50000.00);                 {                                   if ((tradeIn >= price)&&(downPayment >= price - tradeIn))                                 loanAmt = price - tradeIn - downPayment;                         monIntRate = annualIntRate / 12.0;                         annualIntPercent = annualIntRate * 100.0;                         loanAmt= price - downPayment - tradeIn;                                         }                                                 //Output results     cout << fixed << "Price of Vehicle:                "<< setprecision(2) << price      << endl                                   << "Trade in Value  :                "<< setprecision(2) << tradeIn    << endl                                   << "Down Payment    :            "<< setprecision(2) << downPayment << endl                                   << "----------------------------------------"                << endl                                   << "Loan Amount          :                " << setprecision(2) <<loanAmt    << endl                                   << "Interest Rate  :                " << setprecision(2) << annualIntPercent << "%" << endl;```

Could you please show us the line where the error is? I don't think this code is complete as I am scanning for a brace ending main() and not finding it. Is there more to this program?

Welcome to the forum; I hope you will come back often as you progress.

Thank you!

Yes, there is more to the code, I did not paste my return 0; with the return brace ( } ). And Now that I look, I didn't post a copy of the line with the error on my second attempt to paste the code on here. I was testing the program without the equation that keeps giving me the error. The program is running perfectly until it gets to the line in bold.

Thanks again!

Code:

``` //Output results     cout << fixed << "      Honest Dave's Used Cars  " << endl                                   << "Price of Vehicle:                "<< setprecision(2) << price      << endl                                   << "Trade in Value  :                "<< setprecision(2) << tradeIn    << endl                                   << "Down Payment    :            "<< setprecision(2) << downPayment << endl                                   << "----------------------------------------"                << endl                                   << "Loan Amount          :                " << setprecision(2) <<loanAmt    << endl                                   << "Interest Rate  :                " << setprecision(2) << annualIntPercent << "%" << endl                                   << "                  Monthly Payment Options  " endl;     cout << fixed << "24 Months:        " << setprecision(2)                                 << (loanAmt * monIntRate)(1.0 - (1 + monIntRate) - 24) << endl;    //error C2064: term does not evaluate to a function taking 1 arguments   cin.get(); cin.get(); return 0; }```
My professor gave us that exact formula to use in our program to find the monthly payment options. The purpose of that line is to calculate what the users payments would be for 24 months. It needs to also do the same for 36, 48 & 60 months, however; I can't get it to run properly for 24 months.

(loanAmt * monIntRate)(1.0 - (1 + monIntRate) - 24)
I belive that is where your problem is.

if you evaluate
Code:

`(loanAmt * monIntRate)  //assuming you get 12`
then eval this:
Code:

` (1.0 - (1 + monIntRate) - 24) // assuming 13`
so now we have
Code:

```cout <<(12) (13) << endl; //with your error code: I assume that the compiler thinks you mean to call a function that takes an int //but it has no idea what function you intend to call.```
the compiler is like what the hell?
It could also think you were calling a function, hence the error code. like () you are calling 2 functions, and passing a value, but what function do you want
to call? You haven't specified.. strlen, strcat, you get the point
You probably have to divide or multiply, or missing some operator.
That's the problem I think, check the formula again.
