The closet you could get without using special library's(<limits>) would be
unsigned long VarName;
C/C++ have integer types long long and unsigned long long.
and I have not understood what did you mean "without using special library's (<limits>)"? Does this "special library" influence anyway on integral types?
I really do need some sleep, my brain was thinking of calculus limits that can represent infinity at points. Fixed my post, appreciate the clarification .
