Void Functions
Void functions are a programming concept where a function does not return any value to the caller. They are used to perform actions or side effects, such as printing output, modifying data structures, or updating state, without producing a result. This is common in many programming languages, where functions are defined with a 'void' return type or similar syntax to indicate no return value.
Developers should use void functions when they need to execute code for its side effects rather than for computation, such as logging, updating global variables, or performing I/O operations. They are essential in procedural and object-oriented programming for organizing code into reusable blocks that perform specific tasks without returning data, improving code modularity and readability.
