fscanf woes

I'm forced to use plain C and i'm having problems with fscanf....

I'm simply reading in lines from a text file but the last line may
or may not have a \n and the following piece of code gives
an exception at the feof test line (i hate using while).

Any advice on this would be greatly appreciated.

Code:

---

float fData[11];

while(!feof(m_pFile)
{
    for(int i = 0; i< 12; i++)
          fscanf(m_pFile, "%f", &fData[i]);
}

---

You need to test for EOF differently (I think):

Code:

---

while(fscanf(m_pFile, "%f", &fData[i]) != EOF)
{
  // Do whatever
}

---

If you don't like that you could always use fgets():

Code:

---

while(!feof(m_pFile))
{
  char szBuff[BUFF_SIZE];  // Depends on how long the lines are
  fgets(szBuff, 10, fPtr);  // Get 10 chars from file - or till end of line

  if(ferror(m_pFile))
  {
    // Handle the error
  }
  else
  {
    // Convert the character array to a float
  }
}

---

Or something like that. This allows you to test for errors. Otherwise just use the first example - if it doesn't work, come back and explain the errors.

What's so plain about C?! :(

Using a space in the format string will make the scanning function skip several types of whitespace characters:

Code:

---

fscanf(m_pFile, " %f", &fData[i])

---

"Plain" C as opposed to C"++"

In that case, it's just "C" or "C++".
