My data range is N (0 ≤ N < 10^1,000,000)
I am using unsigned long long int, but it's not enough for my data.
Please suggest the data type I should use.

For whatever you are trying to do, there is already software out there for it and you should try to find it rather than reinventing the wheel. – Jeff Hammond Oct 16 '15 at 03:52

1Note: you might want to consider using GMP floats with reasonable a precision instead of integers as `10^1000000` would take ~3MiB to store as an integer. Disregarding the memory requirements, *computing* on ~3MiB integers would be very slow. – Steven Oct 16 '15 at 03:52

`uintmax_t` _may_ be wider integer type than `unsigned long long`. Is so, maybe only 2x the width of `unsigned long long`, but that is far less than `10^1,000,000`. – chux - Reinstate Monica Oct 16 '15 at 03:57
