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

As @Josh said, the correct answer is:

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

You'll need to watch out for the same thing with pointers. This:

int* a, b, c;

Is equivalent to:

int *a;
int b;
int c;
