Hi,

for(int i=0; i<3; i++)
// do something

for(int i=0; i<5; i++)
// do something

If you declare the same variable in two different for-statements, you get the following error in Visual C++:

error C2374: 'i' : redefinition; multiple initialization


This is not standard C++ behaviour. You can change this behaviour with the /Za compiling option, or you redefine the for keyword.

Bye
Alex
