int state[6244]!!!
Hi and thx for any help,
I need to store the integar values of a screen(1280x1024)into an array,but the array must be 6244 elements long.
I checked its sizeof and its 2293672 bytes big,2293kb.
This sounds absurd or maybe its not so absurd,can anyone tell be if this is unrealistic programming and i should find another way.

My first post here is obscure and misleading,so Ill explain better,and if I get any replys Ill be a bit surprised and the glory will be all yours.
what Ive done is made a 2d array[48][128] which is the size of the screen,and that array[48][128] will be filled with integars that refer to a description of a room,(so pc moves into x13,y13 which holds the value of 3,which will give the description of a small passage).
The value of each element of the 2d array is randomly made by a rand function that needs to have an array 6244 elements long so it can assign a value to all the 2d array elements.
dice[6244] is that single dimensional array in question,it would hold that many random numbers and assign them to 2d array[48][128].
dice[6244] when initialised takes 2293672 bytes of space,my question is,is that a bad thing for an application where speed isn't an issue.
It sounds like a lot of space for one array to have.

Are you sure of the size? If it is an array of int, then I believe the size would be 6244 * 4 = 24976 bytes, assuming sizeof(int) is 4 bytes.
2293672 / 6244 is about 367.34, and I find it odd that each element in the array would have a non-integral number of bytes.
EDIT:
Oh, and 48 * 128 = 6144
So, if you need 6144 ints, and sizeof(int) is 4, then your array would be 6144 * 4 = 24576 bytes = 24 KiB.
Even if sizeof(int) = 8, your array would only be 48 KiB, a far cry from the 2.1 MiB that you propose it takes up.

thx laserlight,yeah,2144...
just one question,do you or anyone here think an array of 6144 elements is bad programing,or is it normal?

It's nothing to worry about on todays desktop machines.
