Reading a comma separated file

[nribeck]

I have a very simple question, but I am rather inexperienced in C so I can't figure it out.

I have a bunch of comma separated files, and each field is in quotation marks. Individual records are separated by carriage returns. I want to be able to to go a given record (a specific line in the file) and the read the data in a specific field in that record into an int or a char depending on whether the entry in that field is a number or text.

So, how can I do this?

Open the file
Read the line you require into a string (this in itself is not entirely simple)
Use a pointer to scan along the line to the field you require
Check to see if the field is a number or a string
If it's a number convert the text to the binary number
If it's a string just copy it to your output buffer
Close the file again

Look up functions

fopen
fgets
fread
fgetc
fclose

strtoul

char array (string) handling.
