如何将容器的内容传递给C++中的变量函数

#include <iostream>
#include <vector>

int main() {
    std::vector<int> numbers;
    numbers.push_back(1);
    numbers.push_back(2);
    numbers.push_back(3);

    // 在这里可以对容器中的数据进行操作

    return 0;
}

#include <iostream>
#include <vector>

void processNumbers(const std::vector<int>& numbers) {
    // 在这里可以对容器中的数据进行处理
    for (int number : numbers) {
        std::cout << number << " ";
    }
    std::cout << std::endl;
}

int main() {
    std::vector<int> numbers;
    numbers.push_back(1);
    numbers.push_back(2);
    numbers.push_back(3);

    processNumbers(numbers);

    return 0;
}

#include <iostream>
#include <vector>

int main() {
    std::vector<int> numbers;
    numbers.push_back(1);
    numbers.push_back(2);
    numbers.push_back(3);

    int sum = 0;
    for (std::vector<int>::iterator it = numbers.begin(); it != numbers.end(); ++it) {
        sum += *it;
    }

    std::cout << "Sum: " << sum << std::endl;

    return 0;
}
