c++ - Determine whether two arrays are equal

Question

You are given two arrays to find out if they are equal?

One way to solve it is to use a hash table. How can I accomplish this using a hash table?

Answer 1

Use std::array:

std::array<int, 3> var = {{ 1, 2, 3 }},
                   bar = {{ 4, 5, 6 }};
                   baz = {{ 1, 2, 3 }};

std::cout << std::boolalpha << (var == baz)  // true
                            << (bar == baz); // false
