Sparsh Mittal:
I am allocating 2d array as:
double[gridSize][gridSize] gridInfo;
which works for small dimension, but for large dimension, 16Mb
limit comes.
Walter has decided to introduce a very low limit for the size of
static arrays. (Both Clang and G++ support larger ones).
Would you please tell me how do allocate a large 2d array
(which has to be done as a dynamic array)? It is a square grid
and dimensions are already known.
This allocates your array, filled with NaNs:
auto gridInfo = new double[][](gridSize, gridSize);
If you want to skip most or all the initialization then take a
look at two functions in std.array. In most cases the "partially
initialized" function is enough, and it's quite safer.
