Stack and Queue both are data structures. The main difference lies in their property. Stack follows LIFO (Last in first out) whereas Queue follows FIFO (First in first out). Another difference is that : The stack has only one end..called the top end , which is used to push(insert) and pop (delete) the elements from stack. Whereas in queue insertion takes place from the rear end and deletion takes place from the front end.
