Steps in program planning
No work is done well without proper planning. Therefore, to write a program, the program is completed through a well-planned step-by-step process. The steps in program planning are as follows
(1) Problem identification: The first step in program planning is problem identification. That is, identifying the program to be written for a problem according to the user's needs.
(2) System analysis: After identifying the problem, various information related to the problem must be collected and analyzed, which can be used in the next steps of the programming plan.
(3) Determining the input/output of the program: At this stage, the inputs and outputs required to solve the problem are determined. Some data or information will be used as input in the program and what output will come for the said data, for this the use of some formula or formula is determined.
(4) Algorithm development: Once a complete understanding of a problem and its solution formula is available, the next task is to express in writing the successive steps in the order of solving the problem. That is to develop the algorithm for the program.
(5) Flowchart development: Before creating a program, the steps of how the program will work step by step is called a flowchart. Writing a program requires having a clear idea of how the program will work. Sometimes when the size of the program is very large, it is convenient to make a flowchart. Just as a graph gives a clear idea about several years of data or information, a flowchart can easily understand the core functionality of a program. This allows the program to be analyzed by someone else, making programming easier and saving time. If a problem arises while programming, the problem can be solved by looking at the flowchart. Skilled programmers always create programs by creating flowcharts.
(6) Determination of programming language: The next step of creating a flowchart is a specific language for programming. In that case, some other kind of help can be taken. Note that some software companies prefer a particular programming language for a specific task. Sometimes it is recommended to take the programming language the hard way, such as assembler rather than choosing machine code, or choosing a high-level language. There are many programmers who choose a particular programming language by themselves to provide better working skills and better software.
(7) Writing the program (Program coding): In this step, the program is written using the programming language that has been selected for writing the programming.
(8) Compilation (Program compilation): The program written in high level language cannot be understood by the computer. The program written in high-level language has to be converted into machine language, i.e. compiled. A lot of compiling errors are found while compiling. Compiling can be done perfectly if you follow the instructions of the compiler.
(9) Program testing and debugging: Generally there are some errors in the initial stage. These can be due to various reasons. (Eg- due to lack of clear channel about program language and operating system, complexity of data etc.). These errors in the program are called bugs. The process of making these mistakes in the program is called debugging. These issues can be resolved with the help of appropriate commands. Various types of alpha test, beta test etc. are done before a program is marketed. All these tests are quite helpful in judging the correctness or accuracy of the program.
(10) Documentation: Documentation is the written description of the various stages of program planning such as algorithm, flowcha program coding, bugs, debug, results and instructions required by the user, etc., so that it is easy to solve problems later on. is
(11) Installation: Before satisfactory testing of the programs they are kept in the development library. After satisfactory test results, the programs are loaded into the production library. This library is called install. In many cases, this installation can be very complicated, but it is possible to get good results at this stage if done as a team.
(12) Maintenance: The last step in program planning is maintenance. Maintenance refers to minor changes and enhancements to the program for non-essential reasons. When any software comes to the market, a good one comes to the market. The number of versions of the software is constantly increasing. Software needs to be modified and upgraded for various reasons. In keeping with modernity, advanced versions are brought out. Many of the same software may not work on other operating systems. In that case, the software is later adapted to work on the new operating system.
