SLG IPC Week 4

Did you turn memes on?

• Yes, of course. Who could forget the memes?

• What memes? I don't remember seeing that option.

• I saw the option, but didn't turn them on.

• They're already on by default.

What does default do in a switch statement?

• Executes code regardless if a case matches or not.

• Executes code in the event no case is matched.

• Exits from the switch construct.

• What's a switch statement?

if (minutes > 1)

s = 's';

else

s = ' ';

Can be rewritten as?

• s =

  minutes > 1 ? 's' : ' ';

• s =

  if (minutes > 1)

  's' : ' ';

• s =

  minutes > 1 ? ' ' : 's';

• s = 's' : ' ';

Pick the odd one out.

• While

• Do while

• For

• Switch

What is the difference between a do while and a regular while loop?

Write an example of a for loop.

Which for loop uses a flag properly?

• for (int i = 0; i < 10 && done == 0; i++)

• for (int flag = 0; flag < 10; flag++)

• for (i = 0; flag == 0; i++)

• for (int i = 0; i < 10 && i == 0; i++)

Why shouldn't you use break outside of a switch statement?

• Because my professor told me so.

• Because it violates the single-entry single-exit principle.

• Because it would give me an error.

• Because it can only be used in a switch statement.
