Queue as an ADT (Abstract Data Type) The meaning of an abstract data type clearly says that for a data structure to be abstract, it should have the below-mentioned characteristics: First, there should be a particular way in which components are related to each other 2. dequeue()− remove (access) an item from the queue. follows a FIFO mechanism for data retrieval which means the data which gets into the queue first will be the first one to be taken out from it, the second one would be the second to be retrieved and so on. int t; Queue is an abstract data type which can be implemented as a linear or circular list. void delet(void) //Delete Function Queue, just like any queue (queues for bus or tickets etc.) { printf("\n 2.Delete"); if(rear void display(void) //Display Function } Queues are an important concept of the data structures and understanding their types is very necessary for working appropriately with them.
