比较两个std::vector /数组或者一般的两个stl容器可以使用以下方法：

1. 使用循环遍历元素进行比较：

template
bool compareContainers(const T& container1, const T& container2) {
    if (container1.size() != container2.size()) {
        return false;
    }

    auto it1 = container1.begin();
    auto it2 = container2.begin();

    while (it1 != container1.end() && it2 != container2.end()) {
        if (*it1 != *it2) {
            return false;
        }
        ++it1;
        ++it2;
    }

    return true;
}

2. 使用std::equal函数进行比较：

template
bool compareContainers(const T& container1, const T& container2) {
    if (container1.size() != container2.size()) {
        return false;
    }

    return std::equal(container1.begin(), container1.end(), container2.begin());
}

3. 使用std::memcmp函数比较数组：

template
bool compareContainers(const T& container1, const T& container2) {
    if (container1.size() != container2.size()) {
        return false;
    }

    return std::memcmp(container1.data(), container2.data(), container1.size() * sizeof(typename T::value_type)) == 0;
}

使用示例：

#include 
#include 
#include 
#include 

template
bool compareContainers(const T& container1, const T& container2) {
    if (container1.size() != container2.size()) {
        return false;
    }

    return std::equal(container1.begin(), container1.end(), container2.begin());
}

int main() {
    std::vector vec1 = {1, 2, 3, 4, 5};
    std::vector vec2 = {1, 2, 3, 4, 5};
    std::vector vec3 = {1, 2, 3, 4, 6};

    if (compareContainers(vec1, vec2)) {
        std::cout << "vec1 and vec2 are equal" << std::endl;
    } else {
        std::cout << "vec1 and vec2 are not equal" << std::endl;
    }

    if (compareContainers(vec1, vec3)) {
        std::cout << "vec1 and vec3 are equal" << std::endl;
    } else {
        std::cout << "vec1 and vec3 are not equal" << std::endl;
    }

    return 0;
}

输出结果：

vec1 and vec2 are equal
vec1 and vec3 are not equal
