How did the function do

In a programming language, calling a function causes it to carry out the set of instructions it contains. A self-contained chunk of code known as a function executes a single task or a group of related tasks.

A function can take one or more parameters, which are values when you call it. The arguments are used by the function to carry out its function. The function then uses these inputs to execute its code, returning a value or carrying out an action.

Functions can be used to modularize code, increase its reusability, and minimize code duplication. They can be called from many places in a program. You can carry out a set of instructions by invoking a function rather than writing new code each time you need to complete the same task.
