Problem with while loop... probably common
 

Hi all...

Was wondering if someone could lend a hand - or an eye. I've been trying for hours and was hoping that someone could give me an outside look. I won't beat around the bush, yes this is from a homework assignment, but the assignment is much more than just the loop, and might I add again that I have been working on it for the past couple of days. Here is the loop,

        while(inData)

        {

                inData>>temp1;



                if(temp1>120 || temp1<-30)

                {

                        cout<<"Error: Temperature must be between -30 & 120 degrees." <<endl <<endl;

                        return 1;

                }

                else if (temp1>=120)

                        cout<<setw(72) <<"*" <<endl;

                else if (temp1>=110)

                        cout<<setw(68) <<"*" <<endl;

                else if (temp1>=100)

                        cout<<setw(64) <<"*" <<endl;

                else if (temp1>=90)

                        cout<<setw(60) <<"*" <<endl;

                else if (temp1>=80)

                        cout<<setw(56) <<"*" <<endl;

                else if (temp1>=70)

                        cout<<setw(52) <<"*" <<endl;

                else if (temp1>=60)

                        cout<<setw(48) <<"*" <<endl;

                else if (temp1>=50)

                        cout<<setw(44) <<"*" <<endl;

                else if (temp1>=40) 

                        cout<<setw(40) <<"*" <<endl;

                else if (temp1>=30)

                        cout<<setw(36) <<"*" <<endl;

                else if (temp1>=20)

                        cout<<setw(32) <<"*" <<endl;

                else if (temp1>=10)

                        cout<<setw(28) <<"*" <<endl;

                else if (temp1>=0)

                        cout<<setw(24) <<"*" <<endl;

                else if (temp1>=-10)

                        cout<<setw(20) <<"*" <<endl;

                else if (temp1>=-20)

                        cout<<setw(16) <<"*" <<endl;

                else if (temp1>=-30)

                        cout<<setw(12) <<"*" <<endl;



                }

I'm trying to get the loop to stop at the end of the file (inData), but the problem that I run into is that the last temperature(value) in the file gets printed twice.

Thanks Much,
Nate

Nevermind....
I realized I needed a priming read and put the next read-in to inData at the end of the loop ---- I suddenly feel like a jackass... oh well
