pop function

[gladi]

what are the steps to pop the element from queue in a pop function?

This is my code

Well the basic idea is to copy all of the elements except for the last one into the queue. To do this you might have to create a copy of the array. However, this task would be much easier with an std::vector. You could use the built in pop function, and because it automatically resizes itself, you don't have to have a expandQ method either. Another piece of advice, you might want to put the structure order inside SandwichQueue.

Also, just a piece of advice. Your code will be much easier to follow if you put the implementation of your classes before the main function, or just in a seperate file :)

thank you for your advice
teacher provide this source as it is, so we have to complete those functions

//function to pop
Order SandwichQueue::pop()
{
 
 
 
 
}
 
//push an element, make sure it is not full, if it is call expand funciton
void SandwichQueue::push(const Order& sw)
{
   
 
       
}
 
//Double the queue size, copy the values, and reset back and front
void SandwichQueue::expandQ()
{
 
 
 
}

what if I check if it is empty?!!!

I don't understand what you're asking. Just use what I told you to fill the functions in.
