Global Variables

What is meant by Global Variables?

Global variables are variables declared outside of all functions or blocks in a program and are visible and accessible throughout the entire program. They allow access to data in different parts of a program and have a lifetime that corresponds to the entire runtime of the program.

Typical software functions in the area of "Global Variables":

  1. Declaration and Initialization: Creation and value assignment of global variables outside of functions.
  2. Access Management: Control of access to global variables, e.g., by using keywords like "global" in Python.
  3. Namespace Management: Avoidance of naming conflicts between global and local variables.
  4. Thread Safety: Implementation of synchronization mechanisms for safe access to global variables in multi-threaded environments.
  5. Modular Structuring: Organization of global variables in namespaces or modules for better clarity.
  6. Constant Management: Management of immutable global values used throughout the program.

Examples of "Global Variables":

  1. Configuration Variables: Global settings that control the behavior of the entire application.
  2. Counters: Global variables for tracking program-wide statistics or states.
  3. Error Variables: Global variables like "errno" in C for storing error information.
  4. Database Connections: Global objects for managing database connections in an application.
  5. Logging Configuration: Global settings for the logging behavior of the application.
  6. Language Settings: Global variables for storing the current language in multilingual applications.
