Thanks Don:
I am aware what you meant by fgets() + sscanf() + strncpy() to parse input. At this moment I am working with fscanf() and assuming no missing field of the data.
According to this reference:
Code:
int fscanf ( FILE * stream, const char * format, ... );
Reads data from the stream and stores them according to the parameter format into the locations pointed by the additional arguments.
......
On success, the function returns the number of items of the argument list successfully filled.

My unclear part is: can the number of items of the argument list be separated by newline, i.e. in different rows? In other words, fscanf() keeps looking for the defined items until all of them are found, no matter those items are separated by space, tab or newline?
To give more of my confusion by this code fragment:
Code:
  rewind (pFile);                  //Line 11
  fscanf (pFile, "%f", &f);        //Line 12
  fscanf (pFile, "%s", str);       //Line 13

Line 11: set position of pFile stream to the beginning
Line 12: Look for a float number in one line (e.g. line 1)
Line 13: Look for a string in next line(line 2), or the same line(line 1)?
Code:
  rewind (pFile);                          //Line 11
  fscanf (pFile, "%f %s", &f, str);        //Line 12

This time Line 12 would be Looking for a float number AND a string in the same line (line 1)?
Sorry for this naive question, which bugs me. Thanks a lot!
