Try out some newsgroup dedicated for your platform. off-topic ?? if you don't like the data types or the functions names, just consider the following which is exactly the same : not working : if ((int i = function()) == value) do something working : int i; if ((i = function()) == value) do something the only difference is the variable declaration location... I don't know exactly what the standard says, so others may have a more accurate answer than the one I could give :) Back to top Phlip Guest Posted: Fri Jan 30, 2004 2:40 pm    Post subject: Re: A Query Le Géant Vert wrote: Quote: off-topic ?? if you don't like the data types or the functions names, just consider the following which is exactly the same : not working : if ((int i = function()) == value) do something working : int i; if ((i = function()) == value) do something the only difference is the variable declaration location... I don't know exactly what the standard says, so others may have a more accurate answer than the one I could give Sorry. Your post is off topic because you wrote "the" instead of "The" at the beginning of that paragraph. And we won't get started about the on the end. But the original poster is advised to report their error message to a newsgroup that covers Standard C++ (such as this one). C++ only recently gained the ability to cram a variable declaration inside an expression, so some compilers might have a problem with it. -- Phlip http://www.xpsd.org/cgi-bin/wiki?TestFirstUserInterfaces Back to top Michael Mellor Guest Posted: Fri Jan 30, 2004 3:12 pm    Post subject: Re: A Query Phlip wrote: Quote: Le Géant Vert wrote: off-topic ?? if you don't like the data types or the functions names, just consider the following which is exactly the same : not working : if ((int i = function()) == value) do something working : int i; if ((i = function()) == value) do something the only difference is the variable declaration location...

This is legal: if ( int i = 1 ) { } what the OP is doing: if ( (int i = 1) ) { } is not legal and if it was, what should the scope of 'i' be?
