What does the command "repeat(n) { /* commands */ }" signify in a Karel program?

• A. It signifies a loop that executes indefinitely.
• B. It indicates that the commands will be executed 'n' times.
• C. It defines a set of commands to be run once.
• D. It creates a substitution for the commands defined.

Answer: (B)

The command "repeat(n) { /* commands */ }" in a Karel program specifies a loop structure that allows for a set of commands to be executed a specified number of times, denoted by 'n'. This means that whatever commands are placed inside the curly braces will be performed repeatedly until the count specified by 'n' has been reached. For example, if 'n' is set to 3, the commands inside the brackets will be executed three times in succession before moving on to the next part of the program. This is a fundamental programming concept that enhances Karel’s capabilities, allowing for more complex behaviors and efficiencies in the programming process.
