[kww]

can someone help me with equivalents of this snippets?
I can't understand how -- works

1) for(--iAliveCount; iAliveCount >= 0; iAliveCount--)
2) iDeadPlayers[i--] = iDeadPlayers[--iDeadCount]

-- is just -1.
if it's as a prefix the equation will be handled before the code, suffix will be handled after the code

new i = 1
// i is now 0
somebool[--i] = true

new y = 1
somebool[y--] = true
//y is now 0

PHP Code:

p = 5
test = p--

//test = 5 


PHP Code:

p = 5
test = --p

//test = 4 


The value of p after the p-- or --p lines of code are executed is the same.

how can be -- replaced by ++ in provided code?

They both work the same way, the value just goes in the opposite direction.

PHP Code:

/* so this:             */ for (--iAliveCount; iAliveCount >= 0; iAliveCount--)
/* can be replaced by:  */ for (new i; i < iAliveCount; i++) /* ? */
// am I right?

It depends on what you are doing and how you are using iAliveCount. The first one counts down and the second one counts up.
