Hi John I am trying to create a hyper-cube, multidimensional array, I won't create all the elements of the array, but I need a flat index (the product of the upper bound at each dimension), to index each cell in the created partitions, and this is what will grow exponentially, the flat index value only, I usually use typedef to create my type of a standard type. How can I use it to create bigger types than the standard? how do I check the maximum allowed in the machine I am using? Thank you very much again, Manal 2008/6/25 John Love-Jensen <eljay@xxxxxxxxx>: > Hi Manal, > >> Is there any other types bigger then 'long long"? > > Yes, you can make your own types that are as big as you want, up to the > limits of your platform. > > Whether or not to do so depends....
