Study Notes

Functions in Programming

A function is a block of code that performs a specific task.
Dividing a complex problem into smaller chunks makes our program easy to understand and reusable.
Example: creating a program to create a circle and color it can be broken down into two functions:
- A function to draw the circle
- A function to color the circle

Types of Functions

There are two types of functions:
- Standard Library Functions: Predefined in C++ and available for use.
- User-defined Functions: Created by users to perform specific tasks.
