thank you all for the response. the reason I to know the the allocated
memory size:

i am trying to read a text file with comma seperated values into 
an array. The only way i figuered i could do that is by allocating 
memory and adding new elements to the array. The length of this 
array would be needed if i try to sort it or search the 
contents...

I think keeping track is the only way to know the amount of memory.

thank you all again
