Let’s Revisit


                        A nested loop is a loop inside another loop, where the inner loop executes completely for each iteration of the
                       outer loop.
                        There are 3 types of nested loops, nested for loop, nested while loop and nested do-while loop

                        The break statement is used to exit the innermost loop in a nested loop, transferring control to the next
                       statement after that loop.
                        The continue statement is used to skip the current iteration of the innermost loop in a nested loop and proceed to
                       the next iteration of that loop.

                     2.   When a “break” statement is executed within the outer loop, then the …………………  loop will stop.
                         a.  outer                                      b.  inner

                     3.   ………………… statement is used to exit the current loop.
                         a.  break                                      b.  while

                     4.   The use of a loop ………………… the program code.
                         a.  elongates                                  b.  strengthens

                     5.   In a nested loop structure, which loop completes all its iterations for each iteration of the outer loop?
                         a.  Inner loop
                         b.  Outer loop
                         c.  Both loops run independently
                         d.  The outer loop completes all iterations before the inner loop starts

                     2.  The total number of iterations in a nested loop is calculated by multiplying the iterations of the ………………… loop by
                         the iterations of the inner loop.
