If Statements and Conditionals Drill

A computer chooses between two actions by:

• Flipping a coin

• Using conditional statements

• Guessing randomly

• Asking the user every time

To make Karel navigate a maze, stop before walls, and pick up tennis balls only if they exist, which programming construct should you use?

• for loops

• if statements

• while loops

• variables

If statements help Karel make decisions in a program by:

• Allowing Karel to repeat actions until a condition is met.

• Letting Karel choose actions based on certain conditions.

• Making Karel move forward automatically.

• Stopping Karel from making any decisions.

If Karel didn’t have conditions like if statements, how might that affect the way computers make decisions?

• Computers would not be able to make decisions based on different situations.

• Computers would be able to make more complex decisions.

• Computers would run faster but still make decisions.

• Computers would only use loops to make decisions.

How can if statements make your code more efficient and intelligent?

• By allowing the code to make decisions based on conditions

• By making the code run slower

• By removing all conditions from the code

• By increasing the number of errors
