Why are multiple assignments in one line considered bad style? [closed]

Answer 1

There is no problem as long as you know they should all be the same value.

e.g.

changing

x = y = z = 10;

to

x = y = z = 15;

is very easy.

If however, they are arbitrarily the same, separate assignments convey this, and are easier to change individually for testing.

x = 10;
y = 10;
z = 10;

to

x = 10;
y = 15;
z = 10;

is better than having to break up the line.

The key is what you are telling the next programmer to look at the code (or yourself in 6 months).
