Drawing tables in C

I am sorry to bother folk with such an apparently simple query but I am afraid I can't suss it out.

I have a table of data which I need to print out but the best i can do for some sort of edging is - and |.

is there any way i can make it look better?

fprintf(prn_ptr,"------------------------------------------------------------------------------\n");
fprintf(prn_ptr,"|Rec | Cust | Part | Quant | Customer |Balance |Credit |Error|\n");
fprintf(prn_ptr,"|Type| Code | Number | | Name | |Limit |Code |\n");
fprintf(prn_ptr,"| | | | | | | | |\n");
fprintf(prn_ptr,"|----------------------------------------------------------------------------|\n");
fprintf(prn_ptr,"| | | | | | | | |\n");

Since it looks like you're printing to file, I saved to a csv file last time I needed to do a table.

Windows?

If so, use the line draw characters. Run this program for their values:

Code:

why did you make a prototype of void main???

please use int main first of all.

Second, why would you make a prototype, it seems inefficient...

Sorry about that, but look at the date....

I'm one that keeps mentioning the use of "void main()". I didn't read the code this time because the thing has always worked so I just posted it. It is after all code from 10 years ago..

thanks for the replies. I've not had time to try them out yet. I'll let you know how I get on when I do.
