C++ Big Integer.
Big integer in nothing but a replication of BigInteger class of java that are used to handle a very big integer that could not be handle by long long data type of C/C++ lang.
You can see the full code [HERE][1]
Instead you can also use a header file
include "boost/multiprecision/cpp_int.hpp"
It will provide the same environment that above line code do!
I hope you understand otherwise feel free to ask!

CPP have something like bigInteger class of java…
boost library is one such( I don’t know is there anything else also ?)…
here is a short example for using boost library
#include <iostream>
#include <boost/multiprecision/cpp_int.hpp>
using namespace std;
namespace mp = boost::multiprecision;
#define bint mp::cpp_int
int main()
{
bint a, b;
cin>>a>>b;
cout<<a*b<<endl;
return 0;
}
