# 2.2 Understanding Flowcharts

Pseudocode is a textual description of an algorithm, which can be helpful in understanding complex operations. However, while pseudocode is useful in describing the steps involved in an algorithm, it can sometimes be difficult to visualize the actual sequence of operations.

This is where flowcharts come in handy: they provide a graphical representation of the logical flow and decision-making process behind an algorithm or a program. By using shapes and symbols to represent different operations and decisions, flowcharts can help to make even the most complex algorithms easier to understand.

Additionally, flowcharts can be a useful tool in communicating complex ideas to others, as they offer a highly visual way of mapping out the logical flow of a process. In this way, flowcharts can be an important tool for anyone involved in developing or analyzing algorithms and programs.

Flowcharts use standardized symbols to represent different types of actions or steps...
