REPETITION FROM PPSC AS PER JNTUK KKD.pptx

We must design a Loop, so that before or after each iteration, it checks to see if the task is done. If it in not done, the loop repeats one more time;if task is done,the loop terminates. This test is known as Loop Control Expression.

2. Concept of Loop We must design a Loop, so that before or after each iteration, it checks to see if the task is done. If it in not done, the loop repeats one more time;if task is done,the loop terminates. This test is known as Loop Control Expression.

3. PRETEST AND POST TEST LOOPS

4. Initialization may be Implicit or Explicit. Implicit -No direct initialization of code, depends on pre-existing situation Explicit -we include code to set the beginning values of key loop variables. Infinite Loop if condition is not happened Loop updates INITIALIZATION AND UPDATING

5. INITIALIZATION AND UPDATING

6. Example

7. EVENT AND COUNTER CONTROLLED LOOPS Event C ontrolled Loop: Event changes the control expression from true to false

8. Counter controlled Loop: we know the number of time that the loop is repeated EVENT AND COUNTER CONTROLLED LOOPS
