C++ Increase int size limit

Question

Is there a way in C++ to increase the limit on integers? I want to work with a 13 digit number e.g. 4823423658586. The complier does not allow this.

Answer 1

Since the largest 13 digit integer can be stored using 6 bytes you need a type which will store at least 6 bytes, that type is a long long which can hold 8 bytes.

So instead of

int x=100;

use

long long x=100;
