In C++ why can't I write a for() loop like this: for( int i = 1, double i2 = 0;

Question

or, \"Declaring multiple variables in a for loop ist verboten\" ?!

My original code was

 for( int i = 1, int i2 = 1; 
      i2 < mid;
      i++, i

As long as you can write a valid statement with the comma , operator, it's acceptable.
