Difference between stack /queue and array

Sia ? 4 years, 6 months ago

QUEUES	ARRAY	STACK
Queues are based on the FIFO principle, i.e., the element inserted at the first, is the first element to come out of the list.	In the array the elements belong to indexes, i.e., if you want to get into the fourth element you have to write the variable name with its index or location within the square bracket.	Stacks are based on the LIFO principle, i.e., the element inserted at the last, is the first element to come out of the list.
Insertion and deletion in Queues takes place only from rear and front respectively.	Insertion and deletion in array can be done at any index in the array.	Insertion and deletion in stacks take place only from one end of the list called the top.
Queue has a dynamic and fixed size.	Array has a fixed size.	Stack has a dynamic and fixed size.
Queue can contain elements of different data type.	Array contains elements of same data type.	The stack can contain elements of the different data types.
Different types of Queues are circular queue, priority queue, doubly ended queue.	Different types of Arrays are 1D, 2D, etc.	Stack has only one type.

Liton Barman 7 years ago

As per my knowledge, their is no concept like array function. But you can define a function to manipulate array , as :- return_type func_name(identifier array[n]); Example :- _____________________________________ Int manipulate(int temp[]){ for(int x=0;x<=10;x++){ cout<<temp[x]<<endl; } } _____________________________________ And can call it as :- int hold[]={1,5,3,8,3,9,0,4}; manipulate(hold); // not as manipulate(hold[]) _____________________________________ Thanks....
