Structured Programming: Ensuring Logical Programming

In the world of computer software development , structured programming is a logical construct that allows efficient programming, making it easier to understand and modify. Many programmers define structured programming as one of the subsets of procedural programming. The most important advantage of structured programming is the ability to eliminate the need of using the GOTO statement. In the development of software process, programmers can use structured programming techniques for any programming language to avoid any common errors of unstructured languages. Unstructured languages rely on developers to avoid any structural problems, but the result will be poorly organized programs. Most custom software development services employ modern procedural languages that encourage the use of structured programming. The exact disposition of structured programming varies with the purpose and function of the program. Also called as modular programming, structured programming allows creation of subsets within the whole program structure that interact with each other. Custom software programming always takes the advantage of object oriented programming (OOP), as it employs structured programming techniques for efficient program flow. Structured programming employs a top down design model. It helps developers to map the whole program structure into separate subsections. A set of similar functions is coded in a sub module. This means that the code can be efficiently loaded into memory and that the modules can be used in other programs. After individual module tests, each module is integrated with other modules into the whole program structure. In custom software programming scenario, structured programming tends to include three elements. These three basic elements are:

* Concatenation
* Selection
* Repetition

Concatenation helps logical sequence of statements. The steps in the sequence must progress logically without invoking any errors. Selection allows number of statements to be selected for the execution process to take place. The selection statement contains keywords such as "if", "then", "switch" or "endif". Repetition instructs program to continue functions before requesting further instructions. It includes “for”, “do…until” and “repeat” keywords.
