c++ adding two bool arrays

I have a number as a bool array but I need to do arithmetic operations such as add and subtract and logical such as AND on it with other numbers similar to it. how can do this operations in C++ without need to handle all boolean-specific calculations, and do it simply. an example: 

bool a[10];
bool b[10];
bool c[10];
c = a + b;

You can use std::bitset

#include <bitset>

std::bitset<10> a(4);
std::bitset<10> b("0000001000");

std::bitset c = a.to_ulong() + b.to_ulong();

//Etc.
//You can also use
a[0] = 4; a[1] = 5; //to initialize / access

std::transform can perform a binary operation on pairs of elements from two containers, and put the result into a third container. You can use std::logical_and, and std::logical_or to get the results you want:

transform(a, a+10,
          b, b+10,
          c, logical_and<bool>());

transform(a, a+10,
          b, b+10,
          c, logical_or<bool>());
