sftp keyboard-interactive
SFTP (Secure File Transfer Protocol) supports keyboard-interactive authentication, which means that the authentication process involves user input from the keyboard.
When using SFTP with keyboard-interactive authentication, the server will prompt the user for their username and password, and then may prompt for additional authentication factors such as security questions or a one-time password. The user must respond to each prompt with the correct information in order to complete the authentication process and gain access to the SFTP server.
To use SFTP with keyboard-interactive authentication, you will need an SFTP client that supports this authentication method. Most modern SFTP clients should support keyboard-interactive authentication out of the box.
Using non-placement new expression
Non-placement new expression is a way to create objects in C++ without specifying the memory location where the object should be allocated. It is achieved by using the "new" keyword followed by the type name and constructor arguments.
For example, consider a class called "Person" with a constructor that takes a name and age as arguments. We can create a new object of the Person class using non-placement new expression as follows:
```cpp
Person* person = new Person("John Doe", 25);
```
In this example, the "new" keyword dynamically allocates memory for a Person object and calls its constructor with the provided arguments. The expression returns a pointer to the newly created object, which can be stored in a pointer variable (person in this case).
It is important to note that when using non-placement new expression, it is the responsibility of the programmer to manually deallocate the memory allocated using the "delete" keyword when the object is no longer needed. Failing to do so can result in memory leaks.
