Welcome back to Computer Science class, Year/Grade 11 students! Today, we will be talking about one of the most important concepts in programming - parameters.
As you all know, programming is all about giving instructions to a computer to perform certain tasks. And in order to give these instructions effectively, we need to provide the necessary parameters.
In simple terms, parameters are inputs that we provide to a function or method to perform a certain task. These inputs can be in the form of values, variables, or expressions.
For instance, if we want to write a program to add two numbers, we need to provide the two numbers as parameters to the addition function. Similarly, if we want to print a message on the screen, we need to provide the message as a parameter to the print function.
Parameters play a vital role in programming because they allow us to create dynamic and flexible programs that can handle different types of data and perform different tasks based on user inputs.
To start off today's lesson, we're going to play a fun game called "Guess the Parameter". I will provide you with a function and its output, and you need to guess what parameters were provided to the function to generate that output.
Ready? Let's begin!
