 Que- Make a program by using switch case?

#include<iostream>
using namespace std;

int main()
{
    int button,cont;
    cont=1;
   
    cout<<"1.on"<<endl<<"2.off"<<endl;
    cout<<"water filling switch :- ";
    cin>>button;
    switch (button)
    {
    case 1: cout<<"water filling start"<<endl;
            cout<<"water is now filled at low level"<<endl;
            cont=1;
    break;
    case 2: cout<<"water is not filling";
     cont=0;
      break;
    };
    if(cont==1)
   {
     cout<<"3.close tap"<<endl<<"4.filling continue"<<endl;
    cout<<"water filling switch :- ";
    cin>>button;
    switch(button)
    {
    case 3: cout<<"close tap"<<endl;
            cout<<"filling stop";
            cont=0;
    break ;
    case 4: cout<<"water filling is continue..."<<endl;
            cout<<"water is now filled at medium level"<<endl;
              break;
    };
    if(cont==1)
    {
    cout<<"5.close tap"<<endl<<"6.filling continue"<<endl;
   cout<<"water filling switch :- ";
    cin>>button;
     switch(button)
    {
    case 5: cout<<"close tap"<<endl;
            cout<<"filling stop";
    break ;
    case 6: cout<<"water filling is continue..."<<endl;
            cout<<"water is now filled at high level"<<endl;
            cout<<"cooler is fully filled water filling stops";
            break;
    };
    }
    }
    return 0;
}

Result:-
