Assign single value to multiple variables

I want to开发者_开发问答 assign 0 to all declared values in a single statement.

char r, g, b = 0;

The above only assigns 0 to b but not to the other variables

You can do it two ways:

char r = 0, g = 0, b = 0;

or

char r, g, b;
r = g = b = 0;

---

Tersest form is:

int r,g,b=g=r=0;
