My function will be called thousands of times. If i want to make it faster, will changing the local function variables to static be of any use? My logic behind this is that, because static variables are persistent between function calls, they are allocated only the first time, and thus, every subsequent call will not allocate memory for ...
Hello
Little question concerning app architecture:
I have a python script, running as a daemon.
Inside i have many objects, all inheriting from one class (let's name it 'entity')
I have also one main object, let it be 'topsys'
Entities are identified by pair (id, type (= class, roughly)), and they are connected in many wicked ways. ...
Say I have the following function in a module called "firstModule.py":
def calculate():
# addCount value here should be used from the mainModule
a=random.randint(0,5) + addCount
Now I have a different module called "secondModule.py":
def calculate():
# addCount value here too should be used from the mainModule
a=random.rand...
I've created a variable length array in one function, however I need to refer to this array in a second function. The problem occurs when I put the declaration above main() seeing as its length hasn't been defined yet, my compiler gets angry.
How does one typically go about this?
EDIT:
Here is my code so far.
I need to make the ar...

Hi,
I am trying to define dynamically variables. I am using a function for this, but I don't know how to define the new var as global (because it never created before the function).
is that possible ?
Thanks.

ok, this is what I've built. is it that dangerous ?

I know when it's a matter of accessing memory of a stack frame it'll be through using stack frame pointer but I wonder about how the access to data, BSS segments containing global/static data will be, through using a pointer like stack frame pointer indicating starting point of those segments or instructions address pieces of those segme...
In my .m file for a class named Ad , I have 3 static strings
static NSSTring *AdStateDisabled = @"disable";
static NSSTring *AdStateExpired = @"expired";
static NSSTring *AdStateActive = @"active";
I can simply use these static variables in the current class, but i cannot call them from any other class, is there a way to make these st...
i want to change the value of a variable within a for loop, but then have the new preserved variable changed when the loop finishes

In my iPhone development, I've always used global variables for lots of stuff. The style guide in my new job says we should use context parameters instead. So I need to figure out what that means and how to do that.
Can anyone explain in more detail what this means -- or point me to some code that works this way?
Thanks

Hi, I know how to use the global variables when they are defined in a class, but I have a global variable in a main.
If I want to use it inside a class, which would be the import to access it?
My main is something like this
Main.py:
from EvolutionaryAlgorithm import EvolutionaryAlgorithm
initialTimeMain = 0
if __name__ == '__main__':...
# include <stdio.h>
int x = 5;
int main(void)
{
int x = 7;
printf("output = %d\n", x);
}
The above program shows output as 7.
How to print 5 in c?
thanx...

I have a module named "tooltip" which has a "fade" function which in turn uses a global "element" variable. That variable is a reference to an element of the DOM. I want to update it from another module named "lightbox" so I could just let the "fade" function handle the fade-in effect. All my modules are declared u...

Is there a way that one can implicitly declare top-level variables as global for use in closures?
For example, if working with code such as this:
$a = 0; //A TOP-LEVEL VARIABLE
Alpha::create('myAlpha')
->bind(DataSingleton::getInstance()
->query('c')
)
->addBeta('myBeta', function($obj){
$obj->bind(DataSing...
