Switch case засунуть еще один switch case?

Привет всем!

Как заставить работать Switch case внутри switch case - C++?

#include
using namespace std;

int main()
{
int i;
int j;

switch (i)
{
case 1:
cout << "1. Add data\n" << endl;
break;
case 2:
cout << "2. View data\n" << endl;
break;
case 3:
cout << "2. Individual task\n" << endl;
switch (j)
{
case 4:
cout << "Enter Computer brand: " << endl;
break;

case 5:
cout << "Enter Computer realesed Year: " << endl;
break;

case 6:
cout << "Enter Computer price: " << endl;
break;
}
break;
case 7:
cout << "4. Exit\n" << endl;
break;
}
}
