Lesson 5 Sequence
Objective Describe the sequence construct

Sequence of Statements

Sequence[1] is the easiest construct of structured programming to understand. It is simply the idea that a program is a sequence of statements that are executed one after the other. In more general terms, we can say that a program performs a sequence of tasks one after the other. For example, consider the following GoForARide program.

Put on cycling clothes
Go for a ride
Remove cycling clothes
Take a shower


For this program to work correctly, the statements must be executed in a particular sequence. More specifically, they must be executed in the order in which they appear in the program. Here is a flowchart of this program that may help you visualize the sequence in which the statements are performed.
