If you have more bigger and larger variables, you should use the Boost library. If you are sure your variable is a positive number, you can double your limit by using unsigned types of these integer types. For a short description, mainly short int, int, long int and long long int has these sizes in the memory and their ranges are listed as below, In C++, there are many integer types, these can be found in extended Integer Types docwiki section. In most operations, the exact choice of variable might not be too important, but for larger numbers it is important to understand the most appropriate choice to make to avoid overflow or limit errors which can sometimes be difficult to track down. You need to take into account what the minimum and maximum ranges could be.
