Thread: a shuffle program

I want to cut a tring in half then take each number from eack half and put them on top like this:


1 2 3 4 5 6 7

cut the string in half

1 2 3 4 5 6 7

shuffle

3 7 2 6 1 5 4

any idea on how to do that....thanks

Thanks for the help...

Now if I want to keep on cutting the deck and shuffling till I get to the original .....how do I do it?


Here is my code, but for some reason it is not working?

Code:

 int w,x,y,z,k;
            int count=0;

		char values[]={'1','2','3','4','5','6','7','8'};

		for( w = x = 0, y = z = strlen(values)/2;  x < z  &&  y < strlen(values);   x++,y++ )
		{
			theDeck[w++]=values[x];
		    	theDeck[w++]=values[y];
		    	count++;
		}

		int count2=0;
		for(;;)
		{
			for( w = x = 0, y = z = strlen(values)/2;  x < z  &&  y < strlen(values);   x++,y++ )
			{
				theDeck2[w++]=theDeck[x];
		    		theDeck2[w++]=theDeck[y];
				count2++;
			}
		if (values==theDeck2) break;
		else
		for( w = x = 0, y = z = strlen(values)/2;  x < z  &&  y < strlen(values);   x++,y++ )
					{
						theDeck[w++]=theDeck2[x];
				    		theDeck[w++]=theDeck2[y];
						count2++;
			}
			if (values==theDeck2) break;
                  else continue;
		}

puts(count2);

It seems that my program goes into an endless loop!!!!

This is what I am trying to do.....

I want to cut a deck of 52 cards in half then take each number from from the bottom of the half pile and put them on top like this:

I then want to keep on shuffling in the same manner till I get to the original full deck

example:
1 2 3 4 5 6 7 8

cut the string in half

1 2 3 4..... 5 6 7 8

shuffle

1 5 2 6 3 7 4 8



any idea on how to do that....thanks
