limit on array size

[ajinkya]

hi,
i m writing a program to analyse some data.....i need to declare an array of size ~10^6-10^7...right nw i m unable to work with an array of size greater than 10^5..

please tell me how to declare arrays of such large sizes....

regards,
ajinkya.

i m not having problem with arrays of type "float"...
but problem is there with arrays of "uchar" type

You cannot declare an array larger than the system page file/memory segment size.

Are you using C++? Use a deque instead.
Stuck with C? You are going to have to break that array up into smaller, dynamically-allocated chunks.

Good luck!

I read on one of the forums that declaring array as :

static unsigned uchar

will work....i tried it but the compiler is showing an error ...
actually i m extracting the data from a .root file....

can this static work in this case??

[ajinkya]

sorry it's

static unsigned char
