Anni [7]3 years ago
3 0

Answer:

B. #

Explanation:

Every preprocessing directive must begin with the # character.

For example:

#define : Used to define a macro

#ifndef : Conditional evaluation of macro

#include : Used to include other preprocessor header file as part of the code

As we can see each of the directives begins with the # character. This is a signal to the preprocessor to interpret the subsequent keyword as a directive.

navik [9.2K]
If you encrypt the secret key with someone else's public key, then only that person can decrypt it with his private key. The encrypted content can be freely shared with anyone, however only the intended recipient can retrieve the secret key since he is the only one with the proper private key.
