Question

question: 2 you need to write a program that has karel move if the front is clear, but if it isnt clear, karel will do nothing. which control structure do you need to use? for loop while loop if statement if/else statement none of these

Explanation:

The task requires a conditional action where Karel moves if the front is clear and does nothing if it isn't. An If/Else statement is used for such conditional - based actions where different actions are executed depending on a condition. A For loop and While loop are used for repetitive actions, and a simple If statement would not cover the "do nothing" part when the condition is false.

Answer:

D. If/Else statement
