Creating a Function
Understand how to create functions in C++ by learning their declarations and definitions. Explore how functions have types, names, and arguments, and how to implement their operations. This lesson guides you through writing functional, well-structured code blocks essential for modular programming.
We'll cover the following...
Similar to variables, functions need to be defined before compilation. Every function has a name and a set of operations it needs to perform. The first part of creating a function declaration.
Declaration
The declaration of a function means defining its name, type, and argument(s). This may sound confusing right now but we’ll get the hang of it really soon. Here’s the template for function declaration:
Let’s take a look at the three components one by one:
-
typerefers to the type of value the function produces. In formal ...
