如何确定std :: vector中是否存在某个项？

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

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

    if (std::find(vec.begin(), vec.end(), value_to_find) != vec.end()) {
        std::cout << "Value "<< value_to_find << " found in vector."<< std::endl;
    } else {
        std::cout << "Value "<< value_to_find << " not found in vector."<< std::endl;
    }

    return 0;
}
