Flowcharts And Their Purpose

-

Flowcharts, which have been in use for many years have become more and more specialized as the area using the became better defined. A form of charting we all recognizing is the diagram of electrical circuits. We do not understand these charts, but to the persons schooled and working in electronics, they are highly meaningful. In the same way, the data processing industry has developed its own its set of special symbols for use in picturing the activities in the processing of data.

              The first formal flowchart is attributed to John Von Neumann in 1945. A flowchart is simply a method of assisting the programmer to layout in visual, two-dimensional format, the ideas as to how to organize the sequence of steps or events necessary to solve a problem with a computer. In other word, flowcharts are symbolic diagrams of the operation sequence, data flow, control flow and processing logic in information processing. The charts are read in the same manner that we learned to read a page from the upper left-hand corner page, left to right and top to bottom. The symbol used is simple and easy to learn. flowcharts, very important planning and working tools in programming, have many purposes They:-
  1. Provide Communication:- Flowchart is an excellent means of communication. they quickly and clearly impact ideas and descriptions of algorithms to other programmers, students, teacher, computer operators and users.
  2. Provide an overview:- Flowcharts provide a clear overview of the entire problem and its algorithm for solution. they show all major elements and their relationships. they help avoid the possibility of overlooking important details. leaving incomplete branches, etc. 
  3. Aid in algorithm development and experimentation:- Flowcharts are a quick method of illustrating program flow. it is much easier and faster to try an idea with flowcharts than to write a program and test it on the computer.  experimenting with alternative algorithms is facilitated with flowcharts.
  4. Check program logic:- Flowcharts show all major parts of a program. All details in program logic must be clarified and specified. This is a valuable check for maintaining accuracy in logic flow. 
  5. Facilitate Coding:- A programmer can code the programming instruction in a computer language (code) with more ease with comprehensive flowcharts as a guide. The flowchart specifies all the steps to be coded and helps to prevent omissions our errors.
  6. Provide program revision:- Flowcharts facilitate modification of running programs; they are an indispensable guide in inserting changes and alteration without disrupting program flows.
  7. Provide program documentation:- The flowcharts provide a permanent recording of program logic. It documents the steps followed by an algorithm. A comprehensive carefully down flowchart is an indispensable part of the documentation for each program.

Question: What is Flowchart? Answer:   A flowchart is a pictorial representation of an algorithm. It is often used by programmers as a program-planning tool for organizing a sequence of steps necessary to solve a problem by a computer. It uses boxes of different shapes to denote different types of instructions. The actual instructions are written within these boxes using clear and concise statements. These boxes are connected by solid lines having arrow marks to indicate the flow of operation, that is, the exact sequence in which the instructions are to be executed. The process of drawing a flowchart for an algorithm is often referred to as flowcharting. Why Use Flowcharts? Normally, an algorithm is first represented in the form of a flowchart, and the flowchart is then expressed in some programming language to prepare a computer program. The main advantage of this two-step approach in program writing is that. while drawing a flowchart, a programmer is not concerned with the ...

Rules of Flowchart

-
Flowchart Rules While programmers have a good deal of freedom in creating flowcharts, There are a number of general rules and guidelines, recommended by the American National Standards Institute (ANSI), to help standardize the flowcharting process. Various computer manufactures and data processing departments usually have similar flowcharting standards. Some of these rules and guidelines are  as follow: First chart the main line of logic, then incorporate detail. Maintain a consistent level of detail for a given flowchart.  Do not chart every detail otherwise, the flowchart will only be a graphic representation, step by step, of the program. A reader, who is interested in greater detail can refer to the program itself. Words in the flowchart symbols should be common statements, which are easy to understand. It is recommended to use descriptive titles written in designer's own language, rather than in machine-oriented language. Be consistent in...

Program Development PART 3

-
System Design Technique There are two system design techniques, given as follows: Top-Down Design- The top-down design technique is based on the fact that large problems become more manageable if they are divided into a number of smaller and simpler tasks which can be tackled separately. The top-down design approach is performed in a special way. the main program is written first. it is tested before some programs are written. for this, actual subprograms are replaced with stubs. the study simply tests to see if the data is passed correctly. after the main program is written and check, is module is written and tested in turn. this should first be done without the main program in order to let us stuff is an error occurs. Bottom-Up Design- In the bottom-up approach, it is usually assumed that the basic proteins created will be general enough to be used more than once. using the subroutines, to construct a program save repeating the same lines of code by using it. A bottom-up app...
