Simple User-defined Functions
Explore how to define and call simple user-defined functions in C++. Understand function components, naming rules, and practice writing reusable code modules to improve program structure and efficiency.
Function
We can divide a program into procedural components or modules called functions in C++. We are already familiar with a function, main(). Functions can be reused in a programming technique called the modular or procedural approach, also known as the divide and conquer approach. We should always try to design functions that can be copied and reused in other programs too.
Broadly, there are two types of functions, which we’ll explore in the following sections.
Structure of a function
