I am curious to know that the maximum number of dimensions can be an array in C Programming Language, in 32bits and 64bits.
What is the maximum number of dimensions allowed for an array in C++?

The language doesn't care, you can have as many as you like.
The answer (for you, today) depends on your OS and Compiler.
If you exclude the trivial char array[1][1][1][1][1][1][1][1][1]..., then perhaps char array[2][2][2][2][2][2][2]... is more to your liking.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
It depends on the compiler. The C++ standard apparently recommends supporting at least 256, although it is not required. In a sense all arrays are one-dimensional. Anything else is an array of arrays (of arrays of arrays ...).
However, I can't see any use for 256 dimensions. A char array with 256 dimensions where each dimension was of size 2 would consume over 10 to the power of 77 bytes. That's close to the number of atoms in the observable universe.
On a 32-bit machine you can't directly access more than 4gb, the size of a char array of 32 dimensions with each dimension of size 2. On a 64-bit machine you could have, "theoretically", 64 dimensions, if the compiler allowed it. Of course that would leave no room for anything else to be addressed, like the rest of your program and the OS.
Much more than three dimensions is practically unheard of, so the true answer is that every C or C++ implementation handles more array dimensions than you will ever need in real code.

I think a software renderer must handle more dimensions than 3,the camera changes for example makes use of matrices xyzw calculations,xyztime,UVW=like xyz for textures,ARGB color space
you tell me you can C,why dont you C your own bugs?
It isn't usual for libraries like OpenGL, Direct3D or Vulkan to deal with multidimensional arrays. You can always define your vertices as:Originally Posted by I C everything
To define an object on model space you need just to declare a unidimensional array using this structure...Code:struct vertice_T { float x, y, z, w; // vertice float nx, ny, nz; // normal float r, g, b, a; // color float u, v; // define s and q if you need them... ... };
