Thread: Array in mystack

i have write phase code to Mystack, but its error in declare dynamic array, can you help me, fix it? thanks

Code:

#include "iostream"
using namespace std;
class MyStack{

	public: 
		MyStack();
		~MyStack();
		int Pop();
		void Push(int item);
		void IsFull();
		void IsEmpty();
	private:
		//int this->size=5;
		int *Arr=new Arr[5];
		int index=-1;

};
MyStack::MyStack();
MyStack::~MyStack(){
	delete(Arr);
}
int MyStack::Pop(){
	index=index -1;
	return Arr[index--];
}
void MyStack::Push(int item){
	Arr[index]=item;
	index++;
}
void MyStack::IsFull(){
	if((size-1)==index)
		cout<<" Stack is full";
}
void MyStack::IsEmpty(){
	if(index==-1)
		cout<<"Stack is Empty";
}

void main(){
	MyStack s;
	
	s.Push(6);
	s.Push(3);
	s.Push(2);
	s.Push(5);
	cout<<s.Pop();


	
}

Is this:

Code:

int *Arr=new Arr[5]

supposed to be

Code:

int *Arr=new int[5]

?

thanks but have error
'MyStack::Arr' : only static const integral data members can be initialized

Well yes that's true too; I missed that. All these things are supposed to be done in the constructor, not the definition of the class.
