For loop syntax

In the initialization part of the for loop, is it possible to declare more than 1 variable? I can't seem to find any definitive answer.

That kinda rings a bell. Try two clauses with commas between them and see if it compiles ...

for( int i = 1, int j=1 ; etc

A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi

The two variables have to be the same type, because they have to share the same type declaration:

for (int i=0, j=0; i<10; ++i, ++j) ...
