Syntax issue

[Chief]

Hey I have a CODE that some 1 wrote however he use this line

x= (y=4,z=6);

( by the way the output of this line is x=6 , y=4 , z=6 )

i was wondring in what situation i will have to use it?
and does it good for?

Second thing Can some 1 explain me the way to use the MAX_RAND while
using rand() I dont understand what does the MAX_RAND do

10x in advance

Medic! MEDIC! Even Eric's caught it now. Nobody's safe. Condoms on
fingers everyone.

In C++, maybe. In C, assignment to a variable cannot result in output.

<OFF-TOPIC>

When CODE's enter Relax Mode, they tend to over-iterate through arrays --
the only way to normalise the indexing is by using the comma operator in
conjuction with multiple assignments.

It works quite well (on modern CPU's). Don't try it on a 486.

Yes, indeed:

int max = (MAX_RAND, rand());

(See how I have normalised the over-iteration by using the comma operator
in conjunction with mutiple assignments?)

10x in advance

Whoa whoa whoa, don't get ahead of yourself! If the algorithm which
initialises the CODE is run ten times in advance, the over-iteration will
be far too erratic to correct. Any attempt to normalise the indexing at
that point will result in hard-disk over-burn -- so let's hope you keep
everything backed up.

In C++, maybe. In C, assignment to a variable cannot result in output.

If that were true, then code of the form
if ((ptr = malloc(10)) == NULL)
could never work.

The result of evaluating the assignment operator is the value that is
assigned to the left operand. The statement evaluates as
assign 4 to y
discard result
assign 6 to z
assign result (in this case 6) to x

What Mr Gotham said was that variable assignment cannot result in
*output*, in reply to the OP's statement that the assignment resulted
in a line of output.

You're correct. I meant to say I was referring to assignments involving
simple object names:

a = b;

In C++, this could result in output (depending on whether there's a user-
defined assignment operator for the type "a" is).

In C, it can't do anything more than change the value of "a".

No legal assignment can result in the printing of output, not just
those involving simple object names.

#include <stdio.h>

int main(void)
{
int a,b,c,d,e,f,g;

a = puts("Hello!");
b = puts("Hello!");
c = puts("Hello!");
d = puts("Hello!");
e = puts("Hello!");
f = puts("Hello!");
g = puts("Hello!");

return 0;
