Control structures in c++
Download as PPTX, PDF•2 likes•5,488 views
Control structures in C++ affect how statements are executed and include sequence, selection, and loop structures. Sequence structures execute statements sequentially, selection structures choose between alternatives using if, if/else, and switch statements, and loop structures repeat statements using do-while, while, and for loops. Common control structures are used to make decisions, repeat actions, and transfer control based on conditions.

Control structures in c++
- 2. Control Structures Control structures are used to affect how statements are executed. Sequence structure (Straight line) Selection structure (Branching) Loop structure (Iteration or repetition)
- 3. Sequence Structure Statements are executed one after the other. This is C++'s default behavior!
- 4. Selection Structure Used to choose among alternative courses of action. Making decisions •If •if/else •switch
- 5. If selection structure Used to do something if some condition is “true”.
- 6. If/else selection structure Used to do one thing if some condition is “true”, something else if the condition is “false”.
- 7. Switch Selection structure This is a multiple-Branching Statement where based on a condition the control is transferred to one of the many possible points.
- 8. Loop structure Used to repeat a set of instructions. Looping •Do-While •While •For
- 9. Do-While Loop structure The do-while is an exit-controlled loop . based on a condition the control is transferred back to a particular point in the program.
- 10. While Loop structure The while loop is an entry-controlled loop .
- 11. For Loop structure The For is an entry-controlled loop and is used when an action is to be repeated for a predetermined number of times.
