What is put to output by calling Greeting() twice

The output of calling Greeting() twice depends on the implementation of the Greeting() function. Since the question does not provide the actual code for Greeting(), I’ll provide a general explanation.

If the Greeting() function simply prints “Hello!” without any additional characters or spaces, then calling it twice would result in the output: “Hello!Hello!” (Option B).

If the Greeting() function prints “Hello!” followed by a newline character (or any other separator), then calling it twice would result in the output: “Hello!\nHello!” (where \n represents the newline character).

If the Greeting() function prints “Hello!” with a space after it, then calling it twice would result in the output: “Hello! Hello!”.

Without the actual implementation of Greeting(), we cannot definitively determine the exact output. However, the most common interpretation would be Option B: Hello!Hello!.
