Question

I need to modify my C++ code so it can get the min value of the stack

code is as follows:

#include <iostream>
using namespace std;
#define MAX_SIZE 100

class Stack {
private:
int S[MAX_SIZE];
int top;

public:
Stack()
{
  top = -1;
}

void push(int x)
{
  if (top == MAX_SIZE - 1) {
   cout << "Stack is Full." << endl;
   return;
  }
  S[++top] = x;
}

void pop() {
  if (top == -1) {
   cout << "Stack is Empty." << endl;
   return;
  }
  top--;
}

int peek(){
  return S[top];
}

int isEmpty() {
  if (top == -1)
   return 1;
  else
   return 0;
}

//push min
//if Amin is empty or x <= Amin top
  //Amin push x

//push pop
//if A.top <= Amin.top
  //Amin.pop

//top
//return A.top

//get min
//return amin.top

};

int main() {

Stack s = Stack();
s.push(1);
s.push(2);
cout << s.peek() << endl;



int x = 0;
cin >> x;

}
