Unstructured programming languages or non structured programming languages is difficult with the compare of structured programming languages.

Structured Programming Languages: In Structured programming languages, the entire logic of the program is divided into number of smaller modules of function. Each module is a piece of code that implements a different functionality. The main module calls other modules when they are needed to execute. It is a modular method of writing programs.
