Taking continuos input in an integer array

I'm trying to make a class for adding huge integers. I have 2 arrays both of size 40 I wanted to know if there is any way I can take input with out doing the old school method:

for(int i=0;i<40;i++)
{
   std::cin >> arr[i];
}

In this way I have to take input 40 times. Is there a way to take input like we do in cin.getline?

No, you can't get an array of integers directly, since there's no overload for this type. You'll have to either use third-party library for parsing or define an additional overload for operator>> and array. Example:

#include <iostream>
#include <array>

template <int  N>
std::istream & operator>>(std::istream & is, std::array<int, N> a)
{
  for(int i = 0; i < N; i++)
    is >> a[i];
  return is;
}

int main()
{
  std::array<int, 10> ar;
  std::cin >> ar;
  for(auto & e : ar)
    std::cout << e << ' ';
  return 0;
}
