C++ 如何使用Boost.Filesystem更改当前路径

启动程序时，我想使用current_path（）打印当前路径（“C:\workspace\projects”）。然后我希望能够将路径更改为，比如说“c:\program files”，所以当我再次打印当前路径（）时，我希望打印为“c:\program files”。像这样的

int main()
{
   cout << current_path() << endl;  // c:\workspace\projects
   aFunctionToChangePath("c:\program files");
   cout << current_path() << endl;  // c:\program files
}

intmain（）
{
cout
intmain（）
{
cout如果您想更改另一个目录，那么我建议您试试这个
例如：

boost::filesystem::path full_path( boost::filesystem::current_path() );
std::cout << "Current path is : " << full_path << std::endl;
//system("cd ../"); // change to previous dir -- this is NOT working
chdir("../"); // change to previous dir -- this IS working
boost::filesystem::path new_full_path( boost::filesystem::current_path() );
std::cout << "Current path is : " << new_full_path << std::endl;

boost:：filesystem:：path full_path（boost:：filesystem:：current_path（））；
std：：可以是特定于操作系统的吗？嗯，很简单，我不知道你能做到。非常感谢
boost::filesystem::path full_path( boost::filesystem::current_path() );
std::cout << "Current path is : " << full_path << std::endl;
//system("cd ../"); // change to previous dir -- this is NOT working
chdir("../"); // change to previous dir -- this IS working
boost::filesystem::path new_full_path( boost::filesystem::current_path() );
std::cout << "Current path is : " << new_full_path << std::endl;
