Can anyone help me figure out what's wrong?I can't get the program to compile. I'm using QT and you can just ignore the QT statements (cin, cout).

Code:#include <QtCore/QCoreApplication> #include <cmath> using namespace std; int main(int argc, char *argv[]) { QCoreApplication a(argc, argv); int quit; int continueflag; double aa, bb, cc; double delta; double x1, x2; cout << "Solving quadratic equation" << endl; while (!quit) { cout << "What is the value of a? " << endl; cin >> aa; cout << "What is the value of b? " << endl; cin >> bb; cout << "What is the value of c? " << endl; cin >> cc; delta = bb * bb - 4.0 * aa * cc; if ((delta >= 0) && (aa != 0.0)) { x1 = (-bb + sqrt(delta)/(2.0 * aa); x2 = (-bb - sqrt(delta)/(2.0 * aa); cout << "Equation solution: x1 = " << x1 << " x2 = " << x2 << endl; } else cout << "Equation is unsolvable." << endl; cout << "[ENTER] to try again, [Q] to quit." << endl; cin >> continueflag ; if (continueflag == "Q") quit = 1; return a.exec(); } }
