C. do { code_block } until (condition)

D. while (condition) do { code_block }

A. Executes code_block if the condition is true, otherwise executes the else block

B. Executes code_block if the condition is false, otherwise executes the else block

C. Executes code_block if the condition is true, otherwise does nothing

D. Executes code_block if the condition is false, otherwise does nothing

A. Using the break statement

B. Using the stop statement

C. Using the terminate statement

D. Using the end statement

A. To determine the length of an object
