    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.
