Functions

A function is a collection of reusable code that can be invoked from anywhere in the application. This avoids the need to write the same code again and over. It aids programmers in the creation of modular code. A programmer can use functions to break an extensive program into several tiny and manageable functions.

Solidity, like any other modern programming language, has all of the functionality required to construct modular programs using functions. This section introduces how to create Solidity functions.
