Store value more than range of a variable

Question

Is it possible to store values more than the range of a variable....more than 11 digit numbers without using array... In c++....

Answer 1

Use long int, or if you want more, long long int. E.g.

long long int some_num;
cin >> some_num;

long long long int is however, literally too long and your compiler will agree with me. =^=

Answer 2
