Window()

I'm using this function to get the values for a primitive "graphing calculator". The problem lies in the printing of the function afterwards. I'm using a window(60,1,80,30) in textmode C80. But when i use the \n's it just goes back to the left side of the screen. What can I use to make it stay within the left limit of 60?

Code:

---

void GetMnB()
{
        //clrscr();
        gotoxy(2,2);
        cout << "f(x)=y=Ax^3+Bx^2+Cx+D";
        gotoxy(2,4);
        cout << "A: ";
        cin >> a;
        delline();
        //gotoxy(2,2);
        cout << "B: ";
        cin >> b;
        delline();
        //gotoxy(2,1);
        cout << "C: ";
        cin >> c;
        delline();
        //gotoxy(2,0);
        cout << "D: ";
        cin >> d;
        delline();

        //Got the Info, Printing out the Function...
        gotoxy(2,2);
        delline();
        if(c!=0) printf("%fx^3 ",a);
        if(b<0) printf("\n%f^2",b);
        else if(b>0) printf("\n+%f^2",b);
        if(c<0) printf("\n%fx",c);
        else if(c>0) printf("\n+%fx",c);
        if(d<0) printf("\n%f",d);
        else if(d>0) printf("\n+%f",d);
}
