Question

LAB TASK (STACK) 1)
1)Perform the Stack Program using Array.
2) Array Size is 2999. And Array name is BSCS Stack
3) All Variable Names will be changed.
4) Create Function after main body.

Answer 1

#include <iostream>
using namespace std;


#define MAX 2999


class Stack {
	int top;


public:
	int BSCS_Stack[MAX];


	Stack() { top = -1; }
	bool push(int x);
	bool isEmpty();
	int pop();
	int peek();
	
};


bool Stack::push(int x)
{
	if (top >= (MAX - 1)) {
		cout << "Overflow";
		return false;
	}
	else {
		BSCS_Stack[++top] = x;
		cout << x << " is pushed into the stack"<<endl;
		return true;
	}
}


int Stack::pop()
{
	if (top < 0) {
		cout << "Underflow";
		return 0;
	}
	else {
		int x = BSCS_Stack[top--];
		return x;
	}
}
int Stack::peek()
{
	if (top < 0) {
		cout << "The stack is Empty";
		return 0;
	}
	else {
		int x = BSCS_Stack[top];
		return x;
	}
}


bool Stack::isEmpty()
{
	return (top < 0);
}




int main()
{
	Stack s1;
	s1.push(1);
	s1.push(2);
	s1.push(3);
	s1.push(4);


	return 0;
}
