Introducing Computer Programming

Developing Flowchart

Flowchart is a technique that allows you to represent computer program graphically. Using flowchart you can easily understand the logic of a program. A flowchart represents the logical and operational steps to be performed within the system for transforming the input process into output. Flowchart serves as a basis for discussion and communication between the system analysts and the programmers.  

To create a flowchart, you need to use the following symbols

• Start and Stop symbol
• Processing symbol
• Flow Line symbol
• Input / Output symbol
• Decision making symbol  

While creating a flow chart you need to keep the following points in your mind

• While creating a flow chart only a single flow line comes out from a process symbol.
• Flow direction of a process will always indicate either from left to right or from top to bottom.
• In decision box only one flow line enters and multiple flow lines can come out.
• Only a single flow line comes out from starting process and enters single flow line in stop process.
• Every flowchart contains a logical start and a logical end. 

Illustrative Example

The following figure displays the flowchart of a program for printing grade of employ according to his or her salary:
