A brief overview of programming techniques


In the early stages of computing, people neither have powerful computers nor intricate problems to solve as in today using computers. Both the programmers and the users were mostly computer professionals. Yet, programs were written but, in an unstructured way using a handful of programming languages.

An unstructured program consists of one main program module containing the sequence of statements. The data being used in the program are globally visible. i.e. common to the whole program. The suitability of unstructured programming is mostly limited to beginners who write simple programs or small utilities.

However, with the rising demand for IT applications, the things got changed. Today we have multifarious problems to solve in business, science, industry and everyday life. The most of the computer users are not computer professionals. So we need more sophisticated and user-friendly programs to outfit the current trend in Information Technology. The ability of programmers to organize well-structured solutions to problems is of major importance. In an effort to produce well organized, reliable, easily maintained and efficient programs, a number of guidelines and methodologies were developed.
