示例代码：
#include <iostream>
#include <chrono>
#include <fstream>int main() {// 测量内存操作的执行时间int num = 1024 * 1024;int arry[num] = {2};int arry_tmp[num] = {0};std::ofstream outfile("data.bin", std::ios::binary | std::ios::out);if (!outfile.is_open()) {std::cerr << "Failed to open the file." << std::endl;// return 1;}auto start_mem = std::chrono::steady_clock::now();// 在这里执行内存操作// 例如：循环访问一个大型数组，进行数据处理等memcpy(arry_tmp, arry, sizeof
)
