RE: [GD-General] Variables scope

[Jamie F. <ja...@qu...>]

that's just the way msvc6 is and always has been (i think maybe they added
an option at some point to switch the behaviour?), its scoping of variables
declared in for statements just violates the standard because microsoft
(obviously!) know better. Fortunately they recovered in msvc7.

Subject: [GD-General] Variables scope


Hi there

Few days ago i switched to Visual c++ 6.0 and this is what i discovered.
The compiler accept the following C++ code :

//first loop
	for(unsigned long b=0;b<MeshesArray[current].VerticesCount;b++)
		{
		...//processing
		}
//second loop
		for( b=0;b<not_used*3;b++)
		{
		...
		}

But i thiink i should write the second FOR like this "for(unsigned long
b=0;b<not_used*3;b++)" (i mean i should redeclare 'b' because it came out of
scope)
When i tried the compiler answered me "error redefinition ..." !!!
Did i forget to set an option ;it is a bit strange isn t it?

Greetings
GC
