multiple updates in for statement

[Michael]

Ok how do i implement:

#define MYCONST 10

for(int i=0;i<MYCONST;i++,j--)
{
}

that is I want two items in the last part of the for statement.
Thanks
Mike

I don't see anything wrong with what you've posted. What happens when you
compile/run it?

Your implementation is right.
I do not understand what are you asking...

Assuming j is defined somewhere, you're fine as is. If not how about:

for( int i = 0, j = MYCONST ; i != MYCONST ; ++i, --j )
{
}

Is the problem you forgot to declare and initialize "j"?


#define MYCONST 10

int j = ???;

for(int i=0;i<MYCONST;i++,j--)
{
}

No (well, maybe), but as posted there's a missing comma between i++ and
j--.

Huh?

Eh... Huh? Do you think there are supposed to be two commas?

 

[Richard Herring]

Huh?

Sorry, I take it back. This stupid sans-serif font runs the comma
indistinguishably into the j :-(
