If Else Statment with ctime condition

DarclopsZero (3)
I am try to make a menu for deliver order program.

The menu divide into 3 group which are breakfast, lunch and dinner.
However breaker only available at 6.30am-10pm, lunch available at 11am-1.30pm
and dinner only available at 6.00pm-8.30pm

Let say my current time on the system is 10.30am, and the user select breakfast order. It should not available at this time, and prompt a message to use that the order not available at this period.

How to write the program?

Try using the <ctime> library, particularly the localtime function:
http://www.cplusplus.com/reference/ctime/localtime/

And the struct it stores it in:

I know how to make current time...

Let say my current time is 10.30am, i need to prompt message to user that order is unavailable if the user order any menu.

How to use if...else statement or while statement or switch-case statement for this condition?
