Consider carefully the following code fragment:

int a = 10;

... switch(a)

{

case 5:

cout << "a is 5 ";

case 10:

cout << "a is 10 ";

case 30:

cout << "a is 30 ";

default:

cout << "a is none of the above ";

}

What is its output assuming the value of a is still 10 when executing the switch statement.

a is 5 a is 10 a is 30 a is none of the above

a is 10 a is 30 a is none of the above

a is 10

a is none of the above
