Array Implement of a stack. The stack class definition is shown as follows:

<class Item>

stack

:

std::size_t size_type;

Item value_type;

const size_type CAPACITY = 30;

push(const Item& entry);

pop( );

:

Item data[CAPACITY]; Partially filled array

size_type used; How much of array is being used

You need to write the C++ code or pseudo code for the functions:

(10 points)

// Precondition: size( ) < CAPACITY.

// Postcondition: A new copy of entry has been pushed onto the stack.

(8 points)

pop( );

// Precondition: size( ) > 0.

// Postcondition: The top item of the stack has been removed.
