              B.  Fill in the blanks:
                  1.  There are ………………… types of control flow statements.
                  2.  In Java, there are ………………… types of jump statements.
                  3.  “while” loop and “do while” loop are known as ………………… iteration loop as the increment or decrement does not lie in front of
                    the loop.
                  4.  for(int i=1; i<=10; i=i+1)
                    {

                    }
                     This loop executes for ………………… times.

                  7.  The ………………… loop is known as entry controlled loop as the condition is checked before the loop starts executing.
                  8.  The execution will ………………… when criteria in the condition do not match.
                  9.  In …………………, the flow of control is multidirectional.
                 10.  Conditional statements are of ………………… types.

                    int i=1, j=1;
                    while(i<=5)
                    {
                        System.out.println(i+j);

                        i++;
                        j++;
                    }
