Programming Development Process

A programmer has to go through the following stages to develop a process.

There is five types

I. Defining and Analyzing Problem

2. Designing the Algorithm

3. Coding or Writing the Program

4. Testing Program

5. Final Documentation

1. Defining and Analyzing the Problem

in this step, a programmer studies the problem. He decides the best way to solve this

problem. Studying a problem is necessary because it helps a programmer to decide about the

following things:

• The facts and figures which are necessary for developing the program

• The way in which the program will be designed.

• The language in which the program will be most suitable.

What is the desired output and in which form it is needed, etc.

2. Designing the Algorithm

An algorithm is a sequence of steps that must be carried out before a programmer

starts preparing his program. The programmer designs an algorithm to help visualize

possible alternatives in a program.

3. Coding or Writing the Program

The process of writing a program is a very important step in program development. In

this step an algorithm is converted into program. The program consists of different steps

given in the algorithm. A large number of programming languages are available to write

programs. A programmer selects programming language according to the nature of problem.

4. Testing Program

A program must be tested in the process of program development. This process

verifies the accuracy of a program. The program is tested by executing it again and again.

Different values are given as input and output is checked. The program may not give

required results if it contains any error. The errors must be detected and corrected if the

Output is not correct. All bugs in the program are detected and removed during program

testing. It ensures that the program gives desired results and the problem is solved correctly.

5. Final Documentation

When the program is finalized, its documentation is prepared. Final documentation is

provided to the user. It guides the user how to use the program in the most efficient way.

Another purpose of documentation is to allow some other programmer to modify the code if

necessary. Documentation should be done in each step during development of a program.
