Q 15 - Which of the following transfers control to the labeled statement in Go?

A - break

B - continue

D - None of the above.

Q 16 - Which of the following is true about for loop in Go if for clause that is ( init; condition; increment ) is present?

A - The init step is executed first, and only once.

B - init step allows you to declare and initialize any loop control variables.

C - You are not required to put a statement in init step, as long as a semicolon appears.

D - All of the above.

Q 17 - Which of the following is true about for loop in Go if for clause that is ( init; condition; increment ) is present?

A - After init step, the condition is evaluated.

B - If condition is true, the body of the loop is executed.

C - If condtion is false, the body of the loop does not execute and flow of control jumps to the next statement just after the for loop.

D - All of the above.

Q 18 - Which of the following is true about for loop in Go if for clause that is ( init; condition; increment ) is present?

A - After the body of the for loop executes, the flow of control jumps back up to the increment statement.

B - Increment statement allows you to update any loop control variables. This statement can be left blank, as long as a semicolon appears after the condition.

C - The condition is now evaluated again. If it is true, the loop executes and the process repeats itself (body of loop, then increment step, and then again condition). After the condition becomes false, the for loop terminates.

D - All of the above.
