循环访问存储在C++缓冲区中的数据

#include <iostream>
#include <vector>

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

    for (size_t i = 0; i < buffer.size(); ++i) {
        std::cout << buffer[i] << " ";
    }
    return 0;
}

#include <iostream>
#include <vector>

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

    for (auto it = buffer.begin(); it != buffer.end(); ++it) {
        std::cout << *it << " ";
    }
    return 0;
}

for (size_t i = 0; i < buffer.size(); ++i) {
    // 安全访问
}

for (size_t i = 0; i < buffer.size(); ++i) {
    int value = buffer[i];
    // 使用value进行计算，减少对buffer的直接访问
}

#include <mutex>

std::vector<int> buffer;
std::mutex mtx;

void processBuffer() {
    std::lock_guard<std::mutex> lock(mtx);
    for (size_t i = 0; i < buffer.size(); ++i) {
        // 安全访问和修改buffer
    }
}
