What is Push and POP?

The insertion operation is referred to as push and the deletion operation is referred to as pop

 

What is the easiest sorting method to use?

The answer is the standard library function qsort(). It's the easiest sort by far for several reasons:
It is already written.
It is already debugged.
It has been optimized as much as possible (usually).
Void qsort(void *buf, size_t num, size_t size, int (*comp)(const void *ele1, const void *ele2));

 

Which is simplest file structure?

Sequential.

 



What is data structure?

A data structure is a way of organizing data that considers not only the items stored, but also their relationship to each other.

What are Dynamic data structures

  • Data structures that grow and shrink during execution

What are Linked lists

  • Allow insertions and removals anywhere

Stacks

  • Allow insertions and removals only at top of stack

Queues

  • Allow insertions at the back and removals from the front

Binary trees

  • High-speed searching and sorting of data and efficient elimination of duplicate data items
