Answer / chandra
On Windows platform (32 bit) the max array size is FFFFFFFF.
so if you give int arr[0x3FFFFFFF]; it works in VC++.
and if you try arr[0x40000000]; it gives following error:
error C2148: total size of array must not exceed ffffffff
bytes
We came to this value(3FFF FFFF) by dividing FFFFFFFF (2
power 32) by 4 because each int is 4 byte. so for char
array this value will be full FFFF FFFF.

Answer / rajat paliwal
Actually it depends on which mode you are programming.
if ur workin in normal c complier i.e. in dos (16 bit)
then maximum size for
char-> 65535
int ->65535/2=32767
float->32767/2=16382
..
however if you are working in 32 bit operating enviroment
like in VC++
then the maximum size for char = 2 raisec to power 32..
like that..

Answer / reejusri
Maximum size has nothing to do with only the stack area,
but the area where the array is allocated from. The OP did
not say whether the array was created from dynamic memory
(a.k.a the heap), block or local memory (a.k.a. the stack),
or where automatic variables are declared.
The amount of memory available depends on:
1. The total memory on the platform.
2. The amount of memory allocated to the program.
3. The compiler's settings.

Answer / adnan sheikh
max.size of array is 2^32
Because each process contains:
maximum numbers of segments per process=16KB
largest segment size= 4GB
defines in 32 bits
Types of segments are:
data segment
code segment
stack segment
heap segment and many more.
Hopefully we will satisfies with my answer.

Answer / prasant
It depends on the stack size. If the compiler option is
chosen as default then the default stack size is 1MB and an
array can be allocated upto 1MB size. If the array size
exceeds this limit then the program will throw stack
overflow error.

Answer / sankalp bose
For arrays allocated on the stack, it depends upon the
maximum stack size. For example, for gcc, it is normally 64K
but may be something else. For arrays allocated dynamically
or arrays defined in global/static scope, this number is
different and depends upon the maximum heap area size and
the maximum data segment size respectively. The getrlimit
system call can be used to get all these values.
