如何在一个句子中检查std :: vector中元素的存在？

#include<iostream>
#include<vector>
#include<algorithm>

int main() {
    std::vector<int> vec = {1, 2, 3, 4, 5};
    int target = 3;

    if (std::find(vec.begin(), vec.end(), target) != vec.end()) {
        std::cout << "Element exists in vector."<< std::endl;
    } else {
        std::cout << "Element does not exist in vector."<< std::endl;
    }

    return 0;
}
