    Quick File Input Question


    Just a quick question; I need a little help with fscanf.

    How would you read the following line of text into a program?

    4011900,"4-1.19",4.00,"01S, B19","01S, BA3T","A","0","0"
    4012200,"4-1.22",4.00,"01S, B22","01S, BA2T","A","0","0"
    This is an int, char, float, char, char, char, char, char. My current fscanf statement reads as follows:

    fscanf( circuit_file, "%d,%[^,],%f,%[^,],%[^,],%[^,],%[^,],%[^,]", ...);
    I left out the last part because I do not have any problems with my variable declarations. Where I'm running into problems is reading in "01S, B19". This should be read in as one char, but is being read in as two because of the comma and/or space. Any suggestions?

    If the quotation marks are meant to additionally delimit (rather than be part of) the desired string, then perhaps something like this.
          while ( fscanf( file, "%d,\"%[^\"]\",%f,\"%[^\"]\",\"%[^\"]\",\"%[^\"]\","
                          "\"%[^\"]\",\"%[^\"]\"", &a, b, &c, d, e, f, g, h) == 8 )
    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*
