out of control II 1

Because my last post was sooo long, it was suggested that I start a new thread.
The following code isn't returning the values that I expect:

answers to prompts...

shipmethod 43
zone 02
company 00
filename myinfile
output myoutfile

What I am expecting...

This is UPS zone charge table. It contains all the charges per pound for zone 02.

What I need is for it to read in the file myinfile, put the incrementing header '00420201 ' and the footer 'MGR 20030901010101 and 92 trailing spaces' after every 100 lines read into the myoutfile. The header should only increment the last 4 digits, padded with spaces. I can provide an example offline if necessary.



Thanks in advance,
Donald

I was playing with your code a little and I realized a problem you are having. You asked about isdigit in another thread, and it looks like you are trying to output the char as an int.

You don't have to do it that way. You can just read an int from the input file directly. Assuming your file has all numbers, one per row, and they always are small enough to fit into an int, you can do this:

int currentVal;
zone_chrg_input >> currentVal;
while (!zone_chrg_input.eof())
{
    // All your header stuff ...

    while (line_cnt <= where_i_am && !zone_chrg_input.eof())
    {
        out << setw(5) << setfill('0') << currentVal; //<< endl; for newline
        ++line_cnt;
        zone_chrg_input >> currentVal;
    }

    // All your footer stuff ...
}

PS. I was assuming above that you are using the correct headers (e.g. <iostream> instead of <iostream.h>, etc.) like I mentioned in the previous thread.

 

[dnfrantum]

To make sure I understand what you are saying...
Can I get rid of

ifstream zone_chrg_input;
      zone_chrg_input.open(in_file.c_str());
      ofstream out;
      out.open(out_file.c_str());

Thanks in advance,
Donald

No, because you still use those file streams. In the partial code I posted, you are using

zone_chrg_input

, and you can still use

out

in the way you were doing it.

That last post got me over the hump. Thanks again.



Thanks in advance,
