New to C++ and so lost :S

Code:

115:  out << setw(10) << "Day" 
         << set(10) << t.day << "|" << setw(10) << "Low" 
         << set(10) << t.low << "|" << setw(10) << "High" 
         << set(10) << t.high << "|" << setw(10) << "Normal" 
         << set(10) << endl;

Do you see the error now ??

2. Open the file for input. test for failure, and repeat until a valid filename is entered.
It's not doing that, returning with exit(1); isn't telling it to ask the user again.

Code:

while(fin.fail())
{
  cout << "Enter the name of the data file: ";
  cin >> filename;
  fin.open(filename);
  if(fin.fail())
     cout << "Error opening file: " << filename << endl;
}

would be one way to achieve that.

A line that displays the year and month of the data contained in the report.

A header line that labels each of the columns.

A record for each day of data read in. Each record should contain:
Day (as a number)

Low (F)

High (F)

Average (F) (which is defined as (Low + High) / 2.0).

Difference from normal (F) This is defined as the actual average temp minus the normal temp for the day. Use the actual number

the bottom outputs the average temperature for the month in both Fahrenheit and Celsius.

This is not happening, you call generate_report() but itjust copies the input file directly to the output file.

Read your code closely while keeping those restrictions in mind.

Thanks for replying , yeah i do see what i did wrong

i've updated the code and now i get a parse error but i don't see where it is wrong

In function `void generate_report(ifstream &, ostream &)':
92: parse error before `t'

Code:

...
double avg = 0;
while (read_record(fin,t))
{
  write_record(out,t);
  count ++ 
  avg t = (t.low + t.high)/2.0
  // output average
  cout << avg t << endl;
...

You might wanna address your variable with avg since that's what you're calling it..
So it would be:

Code:

...
double avg = 0;
while (read_record(fin,t))
{
  write_record(out,t);
  count ++ ;
  avg = (t.low + t.high)/2.0 ;
  // output average
  cout << avg << endl;
...

Next time proof read your code more, the 92 infront of the error indicates what line is is pressented on..
The easiest way is to scroll to where the first error tells you it is, see if anything there is missing/wrong, correct that and see if that eliminates the error.

Don't just edit your previus post, today I was in the mood to make my own implementation of your temperature program, now I have no code or description from your part to start from.

I don't get this mindset of, "My question is answered, time to delete my post." Where does this idea come from? If people aren't interested in leaving a record, why don't they use irc? Argh.
