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         


        

Answer 1

I can see why you hope that would work, but---given that even using the rather simple minded teaching tool that

for (i=0; i

is equivalent to

i=0;
while (i

you syntax doesn't work---I can't see why you expected that it would. EAch of the bits need to be valid.
