lets try this one more time, I need some help please!

I also need some help 
--------------------------------------------------------------------------------

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

int main()
{
   char cAgain;
   int iDataset = 1;
   double dRoot, dValuea, dValueb, dValuec;

   cout.setf(ios::fixed);
   cout.setf(ios::showpoint);
   cout.precision(4);

   do
   {
      cout << endl << "****************" << endl
           << "* Data Set " << iDataset << " *" << endl
           << "****************" << endl << endl;
      cout << endl << "Please enter coefficients for quadratic equation"
           << " ax^2 + bx + c = 0" << endl << endl;
      cout << endl << "Value of 'a' : " << endl;
      cin >> dValuea;
      cout << "Value of 'b' : " << endl;
      cin >> dValueb;
      cout << "Value of 'c' : " << endl;
      dRoot = (- dValueb +/- sqrt(pow(dValueb, 2) - 4 * dValuea * dValuec))/ 2 * dValuea;
      cout << endl << "You have entered the equation " << dValuea
           << "x^2 + " << dValueb << "x + " << dValuec << " = 0" << endl;
      cout << endl << "The root to this equation is: " << endl << endl << dRoot;
      cout << endl << "Want to do this again? Y/y/N/n" << endl << endl;
      cin >> cAgain;
      iDataset++;
   } while (cAgain == 'Y' || cAgain == 'y');

   return 0;
}

Here is my program and I dont care if this works as much as I need to know what this error means
program2.cpp:38 : error: expected primary-expression before '/' token
line 38 starts with dRoot =

Hi,
I just took a quick glance at your code, but the problem seems to be in this row:

dRoot = (- dValueb +/- sqrt(pow(dValueb, 2) - 4 * dValuea * dValuec))/ 2 * dValuea;

In C++ you can´t write "+/-", replace the line with the following two lines

dRoot1 = (- dValueb + sqrt(pow(dValueb, 2) - 4 * dValuea * dValuec))/ 2 * dValuea;
dRoot2 = (- dValueb - sqrt(pow(dValueb, 2) - 4 * dValuea * dValuec))/ 2 * dValuea;

... and of course declare dRoot1 and dRoot2.

Did this help?
