C++ itself doesn't place any restrictions on maximum size of arrays.
It depends on your hardware's architecture, compiler, OS, amount of physically available memory...
At this online judge, default memory limit for programs is 32Mb.
That's 33554432 bytes. Divide this number by the size of array's element to get the maximum size of array you can have.

thnx for your rply. suppose i am using visual c++ as compiler and my pc is 64bit and say i have enough available memory, then isn't there any limit?!!
any standard??

With 64-bits you're pretty much limited only by the amount of physically installed memory.
In fact, a 64-bit compiler should be able to compile programs with any array size, as long as total size of all arrays doesn't exceed about 2^64 bytes.
But you won't be able to load the program if you don't have enough memory.
