I've just started to use MSVC 6.0 and I already hate it!Why I cannot compile?for (int i = 0; i<5; i++) ;for (int i = 0; i<5; i++) ;The compiler tells me that "i" is already defined (in the second "for").......!!!!!!!!!!!!!!!! why?????????????????????byethanks

Audetto >> neeeeed helpNo, Visual C++ 6.0 needs help (and IMHO not the kind of help you might get from Visual Hash C .NOT 17.5).Irritating isn't it? As for why, there's a long and a short answer. The short one you know, and as for the long one the mind boggles.

That's very strange indeed since that piece of code compiles fine under Sun Workshop's forte 6.1 compiler...and is perfectly valid too.

Sorry, I should have read the help as soon as I had the problem...I was using Borland C Free Compiler where this code was perfectly legal, ... unfortunatlly MSVC doesn't allow this contruct: the scope of the first "int i" declaration is not only the "for {...}" stantment, but the whole function (or {....}) where it is.

Yep, your code is fine. It's a real shame, but the reality of C++ ...

for (int i = 0; i<5; i++) ;for (int i = 0; i<5; i++) ;The compiler tells me that "i" is already defined (in the second "for").......!!!!!!!!!!!!!!!! why?????????????????????The compiler is right, I don't see any pb in that. You typed "int i", this means you declared a variable named i of type int (the compiler will reserve a memory cell to it), then next line you declare a new variable of type int but with the same name as an existing one!!!for (int i=0;.....for (int j=0;....>>Good and will compile-----------------------------int i;for (i=0;.....for (i=0;....>>Not good but will compile-----------------------------for (int i=0;.....for (int i=0;....>>Will not compileHope this helps.Ab
