您给出两个数组以了解它们是否相等？

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

要解决它的方法之一是使用哈希表。使用哈希表我怎样才能做到这一点？

推荐答案

使用的std ::阵列：

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
