[Insight-developers] more VC++ idiosyncrasies

[Luis Ibanez]

Another way to get around the

for( int i  ... )

VC++  redeclaration problem is to enclose
the "for"  in brackets.

You can put brackets anywhere, and
create a local scope for variables.
That even helps for optimization and debugging.

something like:

{  // begin additional bracket
    // any variable defined here has local block scope
    for( int i=0; i<n; i++) {
    ....
   }
}  // closing additional bracket, end of block scope


{ // begin second additional bracket
   // any variable defined here has local block scope
   for(int i=0; i<n; i++)
   {
   ...
   }
} // closing second additional bracket, end of block scope

Which finally reflects the fact that both for's
are locally concerned and that you're not counting
on both "i" variables to be the same.


..., it isn't pretty either, but, it is a fast solution,
specially when this is not your own code.     :-)
