- Can I create variables during compiling
Can I create variables during compiling time in in c++
I appreciate it if someone has the answer.
Can I create variables during compiling time in in c++. I have an array with 729 elements. I want to divide it into 81 arrays each consists of 9 elements. I do not want to declare 81 arrays. I am thinking maybe there is a way I can use a "for" loop to do it for me.

The title of your post poses an XY problem (see: http://xyproblem.info/ ). Fortunately you have provided a little information about your actual problem.
Consider declaring an array of arrays. int x[81][9]; // 81 arrays of 9 int;
Or using pointer arithmetic.
More sophisticated solutions are available if required.

If you already have defined and initialized the array of 729 elements ...
... then you can easily split it up into an array of arrays without having to touch the sequence of values.
