Write two C++ functions push and pop elects from a stack.

void push (int value);

void pop();

If the stack is full print out "Overflow" and print "Underflow" if the stack is empty. In pop() , you also have to print the element that is popped.

cout "deleted>

The helper functions and main program have already been defined. Write the function definition only for push and pop. Given below is the structure definition:

struct node{

int value;

struct node* next;

}*top = nullptr;

where top is the top of the stack. The following functions/variables are already defined:

int maxSize; //Global variable which defines the maximum size of your stack

bool isEmpty(); //check if the stack is empty

bool isFull(); // check if the stack is full

int stackCounter; //the variable to be incremented/decremented based on push or pop

void display(); // display the current stack. (It does not print out underflow or overflow which should be handled by your function)
