C++ Strings (%u etc)

[xeross]

Hey,

Im working on a script myself atm and i need to put a variable into a query i have the following code :

QueryResult *result = WorldDatabase.PQuery("SELECT `text`, `next` FROM `autobroadcast` WHERE `id` = %u", nextid);

Now i want to know what do the %u etc mean and how do i use them properly.

The variable nextid has been set btw.

Also i've assigned nextid to be a uint32 but it will never reach a number higher then 32 or so what is the best variable type to use for it ?

Thanks for your time, Xeross

%u is unsigned int = uint32

%s = string

and so on..

Standard C formatting ..

What you're referring to is a format specifier for c-style strings. Its used in the standard C library io functions such as printf/sprintf/etc.

The C++ way to add an int/float/whatever to a 'string' (a C++ style string) would be using stringstreams.
