Limitations of Flowcharts
In spite of their many obvious advantages, flowcharts have some limitations, which are as follows:
  1.  Flowcharts are very time consuming, and laborious to draw with proper symbols and spacing, especially for large complex programs.
  2.  Owing to the symbol-string nature of flowcharting any changes or modifications in the program logic will usually require a completely new flowchart. Redrawing a flowchart being a tedious task, many programmers do not redraw or modify the corresponding flowchart when they modify their programs. This leaves the programs and its flowchart in an inconsistent state. That is, the logic used in the program, and that shown in its flowchart, do not match. This defeats the purpose of use of flowcharts as documentation support for programs. To take care of this problem, many companies use software tools, which automatically generate flowcharts directly from the program code. These software tools read the program's instructions and draw flowcharts are drawn from program codes mainly for documentation purpose.
  3.  There are no standards determining the amount of detail that should be included in a flowchart.

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...
