Sequential flow 

In sequential flow of control, statements are executed one after the other in order.

Example:

[Python Class 11] Sequential, conditional and iterative flow - Teachoo - Concepts

 

Conditional flow

When the flow of control of a program is changed based on some condition using control statements, it is termed conditional flow of control.

Example:

part 2 - Sequential, conditional and iterative flow - Concepts - Chapter 6 Class 11 - Flow of Control - Computer Science - Class 11

 

Iterative flow

In iterative flow of control, a statement or block is executed until the program reaches a certain state, or operations have been applied to every element of a collection. 

Example:

part 3 - Sequential, conditional and iterative flow - Concepts - Chapter 6 Class 11 - Flow of Control - Computer Science - Class 11
