#### Introduction to Flowchart drawing tool - RAPTOR

RAPTOR is one of the popular tools to design and evaluate Flowchart. This tool is designed to help students to visualize their algorithms.

Raptor is a simple-to-use problem solving tool that enables the user to generate executable flowcharts. Raptor was written for students being introduced to the computing discipline in order to develop problem solving skills and improve algorithmic thinking.
