Question

You need to write a program that has Karel move if the front is clear, but if it isn’t 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

Answer 1

In this scenario, you want Karel to move only if the front is clear. If the front is not clear, Karel will do nothing. The appropriate control structure for this is:

**If Statement**

An if statement allows you to execute a block of code (in this case, Karel's movement) only when a certain condition is true (in this case, when the front is clear). If the condition isn't met (when the front is not clear), Karel does nothing, which aligns perfectly with your requirements.

So, the most suitable choice is:

**If Statement**
