Is there any limit to declare size of an array??

Question

What maximum size can i give to an array??
like ; my_array[154628050] //what max size can i provide here?
Is it dependent on the machine word length??

Answer 1

Don't exactly know the maximum limit, but if you declare a very large array, you may get segmentation fault.

Answer 2

If I am not mistaken, the array size is an int value.
The maximum int value is 2^32 which is around 2 Billion(if unsigned)
