This behavior can be axiomatized in various ways. For example, a common VDM (Vienna Development Method) description of a stack defines top (peek) and remove as atomic, where top returns the top value (without modifying the stack), and remove modifies the stack (without returning a value). In this case pop is defined in terms of top and remove.

while teaching data structures it is better to teach linked list first and then stacks ..because we can implement stack using linked lists.that is the reason it is better to have a knowledge of linked list and arrays before going to learn other data structures like stack,queue,trees,graphs.one more reason is if we learn linked list first then it will be easy to allocate the size of stack ...
