在c ++中返回指向vector元素的指针

#include<iostream>
#include<vector>

int* getElementPointer(std::vector<int>& vec, int index) {
    return &vec[index];
}

int main() {
    std::vector<int> vec = {1, 2, 3, 4, 5};
    int* ptr = getElementPointer(vec, 2);
    std::cout << "Element at index 2: " << *ptr<< std::endl;
    return 0;
}
