Unit 3 - Flowcharts
Graphic representation of algorithm is known as flowchart which consist of geometric symbols. These symbols are connected by line of arrows called flowlines which indicate the direction of flow of processes or activities. The shape of the symbol indicates the type of operation that is to occur. Flowchart should flow from the top of the page to the bottom. The symbols used in flowchart are standardized.
The main advantage of using a flowchart to plan a task is that it provides a pictorial representation of the task, which makes the logic easier to follow. We can clearly see each and every step and how it is connected to the next step. For example lets look at the discount sales program.
The major disadvantage with flowcharts is that when a program is very large, the flowcharts may continue for many pages, making them difficult to follow and modify.
