State whether the following are valid switch statements. If not, explain why. Assume that n and digit are int variables.
a. switch (n <= 2)
{
case 0:
cout << "Draw." << endl;
break;
case 1:
cout << "Win." << endl;
break;
case 2:
cout << "Lose." << endl;
break;
}
b. switch (digit / 4)
{
case 0,
case 1:
cout << "low." << endl;
break;
case 1,
case 2:
cout << "middle." << endl;
break;
case 3:
cout << "high." << endl;
}
c. switch (n % 6)
{
case 1:
case 2:
case 3:
case 4:
case 5:
cout << n;
break;
case 0:
cout << endl;
break;
}
d. switch (n % 10)
{
case 2:
case 4:
case 6:
case 8:
cout << "Even";
break;
case 1:
case 3:
case 5:
case 7:
cout << "Odd";
break;
}
