2. Control Structures in C++
⚫Controlstructuresareused toaffect howstatementsareexecuted.
⚫Sequence structure (Straight
line)
⚫Selection structure(Branching)
⚫Loop structure (Iteration)

3. Sequence Structure
⚫Statementsareexecuted oneafterthe
other.
⚫This is C++'sdefaultbehavior!

4. Selection Structure
• It is used tochooseamong alternative actions.
• Making decisions
•If
•if/else
•switch
DEPARTMENT OF COMPUTER ENGINEERING ,SCOE,KOPARGAON 4

5. If selection structure
⚫Used todosomething if somecondition is
“true”.
DEPARTMENT OF COMPUTER ENGINEERING ,SCOE,KOPARGAON 5

6. If/else selection structure
⚫Used todoone thing if somecondition is “true” and something
else if the condition is“false”.
DEPARTMENT OF COMPUTER ENGINEERING ,SCOE,KOPARGAON 6

7. Switch Selection structure
⚫This is a multiple-Branching Statement where based on a condition the
control is transferred tooneof the many possiblepoints.

8. Loop structure
⚫Used to repeat a setof
instructions.
⚫Looping
•Do-While loop
•While loop
•Forloop
DEPARTMENT OF COMPUTER ENGINEERING ,SCOE,KOPARGAON 8

9. Do-While Loop structure
⚫The do-while is an exit-controlled loop. Based on a condition the control
istransferred back toaparticular point in theprogram.
Output:

10. While Loop structure
⚫Thewhile loop isan entry-controlled loop
.
Output:

11. For Loop structure
⚫forisan entry-controlled loopand isused whenan action is to be repeated
for a numberof times.
