How can I declare and define multiple variables in one line using C++?

Question

I always though that if I declare these three variables that they will all have the value 0

int column, row, index = 0;

Answer 1

When you declare:

int column, row, index = 0;

Only index is set to zero.

However you can do the following:

int column, row, index;
column = index = row = 0;

But personally I prefer the following which has been pointed out.
It's a more readable form in my view.

int column = 0, row = 0, index = 0;

or

int column = 0;
int row = 0;
int index = 0;
