AVOIDING mutiple inclusion of header file???

[pratik]

HI

HOW CAN WE AVOID MULTIPLE INCLIUSION OF HEADER FILE IN QT??

OTHER THAN WRAPPING .H FILE IN #endif,#include etc

can we give something like:-

<class_ name> *<class_object> in a header file

eg if v have a class EUREKA, can v do:-

EUREKA *e[3];

to make 3 pointer of type class EUREKA in a .h file

if not how can v declare such pointers if v have to use them across other classes

THANK U

I don't mean to be rude, but what does this have to do with Qt? It's basic C/C++. And please don't shout.

You can use forward declarations to avoid including header files in other header files, but they will allow you only to declare pointers and references.

sorry to bother all of u again but i already know how to implement the following in c/c++,

turbo c++,borland c++, c#, VC++(MFC), java(core), the thing is the problem is peculiar

with QT.......... and its giving the error........i didn't mean to shout but i was

desperate......

Please, don't shout and don't start multiple threads on the same topic.

Read about forward declarations.
