Can we use multiples switch statements in just one program?

Question

eg:
{
int a=5,good=10, excellent=15;
switch​(a)
{
case 5:
cout<<"good"<<endl;
break;
switch (good)
{
case 10:
cout<<"Excellent"<<endl;
break;
switch (excellent)
{
case 15:
cout<<"superb"<<endl;
break;
default:
cout<<"worst"<<endl;
}}}
return 0;
}

Answer 1

Yes we can, but need to pay attention, put the nested switch block BETWEEN the 'case' and 'break' statement of the outer switch block;

int x {60}, y {70}, z {80};

switch(x)
{
case 60:
switch(y)
{
case 60:
// x & y = 60
break;
case 70:
// x = 60, y = 70
break;
case 80:
// x = 60, y = 80
break;
}
break;
// more cases for x here ...
}
