Computer Program
A computer is an electronic device capable of manipulating numbers and symbols under the control of a set of instructions known as a computer program directs the computer solve a particular problem and display results. Computer programs are written using programming languages such BASIC, FORTRAN, COBOL, PASCAL, C, C++, ALGOL and so on
Purpose of Program Planning
Suppose we are asked by our teacher to solve an arithmetic problem and we are not familiar with the step involved in solving that problem. In such a situation we will not be able to solve the problem. The same principle applies to the writing computer program also a programmer cannot write instructions to be followed by a computer unless the programmed known how to solve the problem manually.
Suppose we know the step to be followed for solving the given problem but while solving the problem, we forget to apply some of the steps in the sequence. Obviously, we will get the wrong answer. Similarly, while writing a computer program, if the programmer leaves out some of the instructions for the computer alright the instruction in the wrong sequence. Then the computer will calculate a wrong answer this to produce an effective computer program, it is necessary that the programmer writes instruction in the proper sequence. The program must be planned before they are written.
To solve a problem using computer what has gone through the following steps:-
  1. The problem is identified and analysed.
  2. The method for the solution is broken down into a sequence of Elementary tasks.
  3. After the religious of the task, the analysis of the data is done and the information and documents relevant to the program are collected.
  4. The data analysis is 10 followed by identifying the outputs to be produced layout, the input required and operation required to produce the needed output.
  5. Paste on all the above analysis a solution sources are called algorithm is designed it must be kept in mind that the algorithm must be precise, concise and unambiguous.
  6. The next step after algorithm design is to express this algorithm in an appropriate notation.
  7. If in the testing phase some errors are encountered, then looking at the nature of error the program is evaluated and then the errors are removed. This phase is called debugging.

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...
