Question

i have a general case of representing an int in a for loop.

i have some variables(it doesnt really matter) which are instance of menuItem(cocos2d) and the got numbers like this:

w1,w2,w3,w4...

and for the record each one of them is pointer to :

CCMenuItemImage *w1= .....

and they have this property: w1.tag=1 w2.tag=2...
now my basic issue is to run on a loop on this w’s as follow :

for(int i=0;i<10;i++)
{

if ( w%i.tag <5 )
//do here
}

now i am trying to find a way to present the number coming after the w with my index!

its easy with nsstrings BUT what if i need anything else that has a number after it ?

thanks lot.

Naming variables using sequential numbers is almost always a sign that you should be using an array instead.

@interface MyClass
{
    CCMenuItemImage *w[10]; // ten of them!
}
@end

@implementation MyClass

- (id) init
{
     self = [super init];
     if (!self) return nil;

     for (int i = 0; i < 10; i++)
     {
         w[i] = /* make a new one */;
         w[i].tag = i;
     }

     return self;
}

If you ever have homogeneous objects that differ only by their position in a sequence, then you need an array.
