REPETITION FROM PPSC AS PER JNTUK KKD.pptx
- 1. REPETITION
- 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
- 6. • 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
- 8. Example
- 9. EVENT AND COUNTER CONTROLLED LOOPS Event Controlled Loop: Event changes the control expression from true to false
- 10. Counter controlled Loop: we know the number of time that the loop is repeated EVENT AND COUNTER CONTROLLED LOOPS
- 11. LOOP COMPARISONS
