Top Forums Programming C++ Map using a Vector as a Value Type? Post 302430710 by Corona688 on Friday 18th of June 2010 12:00:11 PM

A C++ map definitely isn't a hash table. A hash table is a map, but not all maps are hash tables... Hash tables have strong advantages but plenty of pitfalls. A C++ map is a more general purpose list-based thing.

That's beside the point here, though. You're checking for the string 'end', which your document doesn't have, so your loop will never stop; so you may be trying to add strings which weren't read to your map.

Why not ask cin when it's done instead?

Code:
while(cin)
{
        ...
}

Also, put debug statements in your code. Output lines to cerr so you can track what your program's doing.

NAME
nisplus_table - Postfix NIS+ client SYNOPSIS
postmap -q "string" "nisplus:[name=%s];name.name." postmap -q - "nisplus:[name=%s];name.name." <inputfile DESCRIPTION
The Postfix mail system uses optional lookup tables. These tables are usually in dbm or db format. Alternatively, lookup tables can be specified as NIS+ databases. To find out what types of lookup tables your Postfix system supports use the "postconf -m" command. To test Postfix NIS+ lookup tables, use the "postmap -q" command as described in the SYNOPSIS above. QUERY SYNTAX
Most of the NIS+ query is specified via the NIS+ map name. The general format of a Postfix NIS+ map name is as follows: nisplus:[name=%s];name.name.name.:column Postfix NIS+ map names differ from what one normally would use with commands such as niscat: o With each NIS+ table lookup, "%s" is replaced by a version of the lookup string. There can be only one "%s" instance in a Postfix NIS+ map name. o Postfix NIS+ map names use ";" instead of ",", because the latter character is special in the Postfix main.cf file. Postfix replaces ";" characters in the map name by "," before making NIS+ queries. o The ":column" part in the NIS+ map name is not part of the actual NIS+ query. Instead, it specifies the number of the table column that provides the lookup result. When no ":column" is specified the first column (1) is used. EXAMPLE
A NIS+ aliases map might be queried as follows: alias_maps = dbm:/etc/mail/aliases, nisplus:[alias=%s];mail_aliases.org_dir.$mydomain.:1 This queries the local aliases file before the NIS+ file. SEE ALSO
