The user should input the current date, time, and the number of days until the meeting. 
The program should display the scheduled meeting date and time in a user-friendly format.

Pseudocode:
Get the current date and time from the user.
Get the number of days until the meeting.
Add the number of days to the current date using LocalDateTime.plusDays().
Format the meeting date and time using DateTimeFormatter.
Display the formatted meeting date and time.

START
    Prompt user for current date and time
    Prompt user for number of days until the meeting
    Add the number of days to current date
    Format the new date and time
    Display the formatted meeting date and time
