// bitset::all
#include <iostream>       // std::cin, std::cout, std::boolalpha
#include <bitset>         // std::bitset

int main ()
{
  std::bitset<8> foo;

  std::cout << "Please, enter an 8-bit binary number: ";
  std::cin >> foo;

  std::cout << std::boolalpha;
  std::cout << "all: " << foo.all() << '\n';
  std::cout << "any: " << foo.any() << '\n';
  std::cout << "none: " << foo.none() << '\n';

  return 0;
}

Possible output: 
Please, enter an 8-bit binary number: 11111111
all: true
any: true
none: false
