In this part we can learn about the different flow chart symbols used in the computer programming and the algorithm based questions and where they are applied in the Computer Aptitude.

The Flow chart and Pseudo codes are generally used for the better understanding in the computer language. They are used in various forms and predominantly used. Also this can be stated as the breakdown of a complicated process into a simple procedure with the use of diagrammatic representation while the meaning and the procedures of the original one and the codes are not changed.

A Diamond represents the DECISION and they decide the further process in a program and there can be two possibilities as the outcome and decides the flow of the diagram.

The Connector represents the relationships between the different shapes in a program or calculations and show the flow of the diagram.

A rounded character represents the jump within the process and is also used to indicate a jump in the program /calculations from one point to another.
