Flowchart — Visual Representation of Algorithms

In the previous section, we have learnt to write algorithms, i.e. step-by step process of solving a problem. We can also show these steps in graphical form by using some symbols. This is called flowcharting.

A flowchart is a visual representation of an algorithm. A flowchart is a diagram made up of boxes, diamonds and other shapes, connected by arrows. Each shape represents a step of the solution process and the arrow represents the order or link among the steps.

Flowchart Symbols:

Flow chart for simple interest calculation.

Flow chart to find bigger number among two numbers.

Flow chart to print the number from 1 to ∞.
