Question: Write about Algorithm.

 Answer: Algorithm is a sequence of precise and unambiguous instructions solving a problem infinite number of operations; these instructions are in use language i.e. independent of any programming language.

 Characteristics- An algorithm represents the logic of the processing be performed. However, in order to qualify as an algorithm, a sequence of instructions must process the following characteristics:

  1. Each and every instruction should be precise and unambiguous.
  2. Each instruction should be such that it can be performed in a finite time.
  3. One or more instructions should not be repeated infinitely. This ensures that the algorithm will ultimately terminate.
  4. After performing the instructions that are after the algorithm terminate the desired results must be obtained.
Properties: the following are the important properties of an algorithm

  1. An algorithm should terminate after a finite number of steps. Means that when it is executed, it should come to a stop after executing a finite number of an assignment, decision and repetitive step.
  2. An algorithm should be simple, each step of the algorithm should precisely defined that is the step must be unambiguous so that the computer understands them properly
  3. An algorithm should be universal and lead to a unique solution of a problem.
  4. An algorithm should take certain precise inputs or initial data and output should be generated in the intermediate as well as the final steps of the algorithms. It should also have a capability to handle some unexpected situations which may arise during the solutions of a particular problem.
  5. An algorithm should be complete in  itself. That is, it should be able solve all problems of a particular type (for any input data) for which designed.

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...
