How can I add an element in the given stack?

Question

I am trying to add 66 int the given stack {10,100,5,99,20} but I am hitting error in line 7. My code:
#include<iostream>
#include<stack>
using namespace std;
int main(){
stack<int>s;
s={10, 100, 5, 99, 20};
for (int i=0;i<=5;i++){
s.push(66);
}
cout<<s.top();
return 0;
}

Answer 1

s={10, 100, 5, 99, 20};
This line isn't valid. stack doesn't work like this with an initializer list.
You can use a loop to push the elements to the stack though;
for (auto& num: {10, 100, 5, 99, 20}) {
s.push(num);
}
Then you can just push 66 or whatever int as normal.
s.push(66);
