Algorithm a procedure for solving a mathematical problem (as of finding the greatest common divisor) in a finite number of steps that frequently involves repetition of an operation; broadly : a step-by-step step-by-step procedure procedure for solving a problem or accomplishing some end especially by a computer
Flowchart : a diagram that shows step-by-step progression thro through ugh a procedure or system especially using connecting lines and a set of conventional symbols ADVANTAGES OF USING FLOWCHARTS Communication: Communica tion: Flowcharts are better way of communicating communicating the logic of a system to all concerned. Effective analysis: With the help of flowchart, problem can be analysed in more effective way. Proper documentation: Program flowcharts flowcharts serve as a good program documentation, which is needed for various purposes.
Efficient Coding: The flowcharts act as a guide or blueprint during the systems analysis and program development phase. Proper Debugging: The flowchart helps in debugging process. Efficient Program Maintenance: The maintenance of operating program becomes easy with the help of flowchart. It helps the programmer to put efforts more efficiently on that part LIMITATIONS OF USING FLOWCHARTS Complex logic: Sometimes, the program logic is quite complicated. In that case, flowchart becomes complex and clumsy. Alterations and Modifications: If alterations are required the flowchart may require re-drawing completely. Reproduction: As the flowchart symbols cannot be typed, reproduction of flowchart becomes bec omes a problem. The essentials of what is done can easily be lost in the technical details of how it is done.
Types of flowchart Program Flowchart is a graphic representation of an algorithm, often used in the design phase of programming to work out the logical flow of a program. It demonstrates how a program works within a system. System Flowchart helps to understand how complex systems work. Systems analyzed may be anything from businesses, through biological population models, to the impact of social policy, etc.
Flowchart Templates A flowchart lets you visualize a process for your business. These processes are often unique to your specific organization so it may seem counterintutive to want to use a template. However, every flowchart shares some common elements like a starting symbol, a few process steps, and an ending symbol. If you just can't work with a blank screen, a basic flowchart template will help you get started.
Flowchart Symbols+ Flowcharts use special shapes to represent different types of actions or steps in a process. Lines and arrows show the sequence of the steps, and the relationships among them. These are known as flowchart symbols. Basic Flowchart Symbols For most flowcharts, these five basic symbols are all you will need.
On-Page Connector – – Continues the flow on the same page. On-page connectors are defined with an alpha character starting with A. Off-Page Connector – – Continues the flow to another page. Off-page connectors are defined with an alpha character and the reference to the page to which the flow is i s going, or the page from which the flow has come, depending on the nature of the connector.
Flow-Direction Indicator A symbol that indicates the parallel, sequential, temporal, or spatial relationships among the entities represented by the symbols on a flowchart.
