C++：检查一个向量中的元素是否大于另一个具有相同索引的元素的有效方法？

#include <iostream>
#include <vector>

bool checkVector(const std::vector<int>& vec1, const std::vector<int>& vec2) {
    if (vec1.size() != vec2.size()) {
        return false; // 向量大小不一致，无法比较
    }

    for (size_t i = 0; i < vec1.size(); i++) {
        if (vec1[i] <= vec2[i]) {
            return false; // 存在元素不满足条件
        }
    }

    return true; // 所有元素都满足条件
}

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

    if (checkVector(vec1, vec2)) {
        std::cout << "All elements in vec1 are greater than corresponding elements in vec2." << std::endl;
    } else {
        std::cout << "There are elements in vec1 that are not greater than corresponding elements in vec2." << std::endl;
    }

    return 0;
}
