A Query

Hello Grp,

Why is this erroneous
if((uint32 ulStart = MInfo.ulGetNewDataStart()) ==
MInfo.ulGetNewVctrTableStart())
//do something

this works
uint32 ulStart;
if((ulStart = MInfo.ulGetNewDataStart()) == MInfo.ulGetNewVctrTableStart())
//do something

Thanks in advance.

Regards,
Naren.

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.

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?
