C++是否具有顺序搜索功能？

#include <iostream>
#include <vector>
using namespace std;

int main() {
    vector<int> seq = {1, 2, 3, 4, 5};
    int target = 3;
    int result = seq.size();

    for (int i = 0; i < seq.size(); i++) {
        if (seq[i] == target) {
            result = i;
            break;
        }
    }

    cout << "元素 " << target << " 的位置是：" << result << endl;
    return 0;
}
