nmea sentence

Hey people,

Im working with NMEA sentences and am having trouble parsing them. The NMEA sentence is delimited by commas. So, I have to parse this line and store the data inbetween the commas.
i.e. ,temp,temp1,temp2,,

The problem is I am using a program called wiz-c to do this and it does not have methods normally made available in C++.

So I have came up with this bit of code

Code:

---

skipComma(1);      // skips the first comma
ch=WaitRx();        // reads data into a temp ch variable
if(ch!=',')              // if ch does not equal comma then
{
data=ch;              // Store ch in variable called data
}
else
{
data=''          // If ch does equal comma then set data to nothing
}

---

I have to do this 10-15 times and record the data in each field.
This doesnt seem to work, anyone got any ideas?

You only store a single character, store an entire string instead. Read characters until a comma is found, then store the entire string you got so far and start over. Repeat until EOF (end of file) is found.

Code:

---

list all_words = EmptyList();
string current_word = "";

while(!Eof())
{
  char current_char = GetChar();

  if(current_char == ',')
  {
      all_words.add(current_word);
      current_word = "";
  }
  else
  {
      current_word += current_char;
  }
}
