How do you execute multiple commands in a single line in Karel?

• A. By using commas to separate commands
• B. By using a colon to separate commands
• C. By using a semicolon to separate commands
• D. By chaining commands with an ‘and’ operator

Answer: (C)

In Karel programming, executing multiple commands in a single line is accomplished by using a semicolon to separate the commands. This allows Karel to understand that several instructions should be carried out sequentially without needing to break them into separate lines. For example, if you wanted Karel to move, pick a beeper, and turn left all in one go, you could write it as `move(); pickBeeper(); turnLeft();`. Each command is terminated by a semicolon, signaling the end of one action before the next begins. This syntax keeps the code clean and concise, making it easier to read and understand while still ensuring that Karel executes each command precisely in the order listed. This method is fundamental in programming as it helps reduce the number of lines of code while preserving the clarity of the commands being executed.
