Program Development of life cycle

 Program development is not a single activity but a multi-step process. Each step comprises of specific type of activities. All the steps  of program development put through are often referred to as program development life cycle. 

Program development  life cycle steps are given below -

1. Understanding the problem -

For writing a program , you have to understand the problem first,  unless you understand the problem clearly you will not be able to write the program.

2. Planning the solution-

Planning the solution means finalizing all those steps that are to be carried out for solving the problem. This step is often referred to as algorithms development or logic development phase.

3. Coding -

Refer all above mentioned steps and note that these steps are simply a plan on paper for attaining a solution, not the exact solution. The exact solution has to exist in the form of command written in computer language.

4 .Editing, Compiling and Executing-

In the phase, program is written on computer using a text editor. After entering the program in compiled so that the sentences of the program gets converted into machine language.

5. Debugging -

Newly development program may have few error in it. These errors can occur due to various reasons. Either you may have forgotten some of the steps or you may have performed wrong operations or you may have used wrong logic in the program. All such type of errors have to be found our in the program and corrected so that the program gives correct results. This process finding mistakes in the program and correcting them called debugging.

6. Documentation -

A correct program is of very little use. Unless it is supported by full description in writing. Detailed description of the program is called documentation.
