如何在C++中修复向量的“下标超出范围”错误？

#include <iostream>
#include <vector>

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

    try {
        int value = vec.at(10);  // 访问超出范围的下标
        std::cout << "Value: " << value << std::endl;
    } catch (const std::out_of_range& e) {
        std::cout << "Error: " << e.what() << std::endl;
    }

    return 0;
}

Error: vector::_M_range_check: __n (which is 10) >= this->size() (which is 5)
