In MS C (at least in Quick C, which I use), you can use arrays
larger in size than 64k in huge models, but you cannot just set
aside space for them by using a line like

char bigarray[150000];

You have to use one of the memory allocation functions (e.g.
malloc, calloc) to explicitly request storage for your array
before you use it. These functions return a pointer to the
allocated space if successful, or else NULL if the allocation
failed.

For very large arrays, there are also some restrictions about
the size of each element being a power of 2, I seem to remember,
but if you are just using char or int, this should not be a problem.
