A while() loop is used to:

• Execute a section of code until a condition is met.

• Check an input repeatedly.

• Wait a specified length of time.

• Ensure that the battery has enough power for an operation.

"CW" is an abbreviation for:

• Constant Wave

• Charge Wait.

• Clock Wait.

• Clockwise.

An autonomous robot is one that:

• Uses its own intelligence or program to handle different situations.

• Requires a human operator to carry out its tasks.

• Is able to respond to joystick commands.

• Has mechanisms to perform a variety of operations.

The sleep_for() command will cause your program to:

• Turn off the robot controller briefly.

• Turn off all motors briefly.

• Pause for a certain amount of time

• Stop and only restart after user input.

The code "if (students == 14) {conditional code};" ___________.

• Will not cause an assignment.

• Will cause an assignment and execute the conditional code.

• Will only execute the conditional code if the value of students is 14.

• Will never execute the conditional code.

Assuming that "final" is an int variable, what is the value of "final" after the following code fragment? final = 17; final /= 3;

• 5 2/3

• 6

• 5.666

• 5

Signed ints versus unsigned ints:

• Wrap at the same value.

• Wrap at a lower value

• Wrap at a higher value.

• One never wraps, whereas the other always does.

You have a bin full of good tires ("tires"), and you need to know how many will be left over ("leftovers") after you take out all the full sets of 4. The code would look like:

• leftovers = 4 % tires

• leftovers = tires / 4

• leftovers = tires – (tires /4)

• leftovers = tires % 4

An if-else statement is used when:

• You need to do one thing or both things.

• You need to do one thing or the other, but not both.

• You need to do one thing, the other, or neither.

• You need to do both things, or neither.

When your computer compiles your program, it is

• Converting your 'C++' program to machine language.

• Sending the program to the robot brain.

• Creating or editing 'C++' language statements.

• "Piling" program statements, one after another.
