A structured approach is defined as a process in which steps are taken to develop a program. There are 5 simple steps to follow whilst following the structured approach;

1. Define and Understand the program

We define the problem statement and classify what the boundaries of the problems are. We try to understand what is required and what solutions, must we use for the problem.

2. Plan & Design

This is a stage where we determine the requirements such as variables or functions to solve the problem. The programmer gathers all the required and necessary resources to solve the defined problem a programmer has stated for their project.

3. Implementation

Programmers must develop a step-by-step procedure to solve the problem using specifications given in the planning and designing stage. this is the practical part where programming is occurring and languages are involved.

4. Testing & evaluating

This stage checks if the code is written in the implementation stage is solving the problem. This means the programmer must test the program whether it is solving the problem for various input data values or not. The programmer also must test whether it is providing the desired outcomes of the problem.

5. Maintaining

Finally, the maintaining stage is when the program is actively used by the user. If any enhancements are found or required in this phase, all stages of program development will be repeated in order to make them.
