please refer the kb6 book page no 349. the book says

The next example demonstrates a for loop with multiple variables in play. A
comma separates the variables, and they must be of the same type. Remember that
the variables declared in the for statement are all local to the for loop, and can't
be used outside the scope of the loop




why is this happening ?

I don't have the book for reference. May be the book refers to declaring more than one type in the for loop.

In a for loop , only one type of variable can be declared, according to the KB book.
