reading strings into a linked list

[Guest_imported]

Hi all,

I have a file containing records as follows:

1634 2439484 the guess who - Get Your Ribbons On

I need to load this into a linked list containg:" int, int char[256],char[256]". the split between the 2 chars is (obviously?) at the hyphen on the input file.I have been attempting all manner of fscanf arguments along the lines of the code given below, but I can not get the fscanf to add the white spaces.

Can anyone help me with this!

regards

Tom

void read_file (void) {

lstptr = (INPUT*) malloc(sizeof(INPUT));
fscanf(textfile,"%s %s %s %s", lstptr->field0, lstptr->field1,
lstptr->field2, lstptr>field3);
rcdCtr++;
lstptr->next = endOfInputPtr
endOfInputPtr = lstptr;
}
fclose(textfile);
std::cout << &quot;Records read in.... &quot;<< rcdCtr <<'\n';
return;
}

there you shopuld try to use fgetch and fread. They just read bites, ignonring all the nulls, spaces, newlines...

Try reading in each line using fgets() and then parsing the line with sscanf(), strtok() or even strtol(). fscanf() can be a tricky function to use and is often best avoided.

Also, you have a common error in your loop where you use the feof() function to test for end of file at the top. The problem is that feof() doesn't evaluate the stream passed to it, so it won't detect end of file until the code inside the loop has already detected it, in this case fscanf(). This will cause you to read the value of EOF into your variables, if this conversion is possible.
