Library Functions in QBasic | SEE & Class 9 | Longest String | Part I | Sushan Hada

Welcome to our in-depth tutorial on Library Functions in QBasic, specifically tailored for Grade 9 and 10(SEE) students. Whether you're just starting your journey into programming or looking to enhance your QBasic skills, this video will provide a detailed exploration of library functions and how they can elevate your programming experience. Chapter 1: Introduction to QBasic We kick things off with a brief overview of QBasic, the high-level programming language developed by Microsoft. Understanding the fundamentals of QBasic is essential before diving into the world of library functions. Imagine you're building a house. You wouldn't want to craft every single brick yourself, right? That's where library functions come in. They're like pre-made building blocks, ready to be used in your programs to perform specific tasks. They save you time, effort, and code, making your life (and coding) much easier. Chapter 2: The Importance of Library Functions Learn why library functions are crucial in programming and how they can significantly simplify complex tasks. We'll discuss how library functions serve as pre-written code snippets, saving time and effort while promoting code reusability. Think of it like this: Each tool in the toolbox is a library function, with its own special ability. Want to add two numbers? Use the + function. Need to know the length of a string? The LEN function is your friend. Feeling fancy and want to find a specific character in a sentence? The MID$ function has your back! Exploring the Function Toolbox: Now, let's crack open the toolbox and see some of the coolest library functions you can use in QBasic: String Manipulators: LEN: Find the length of a string (like counting the bricks in a wall). LEFT$: Extract a specific number of characters from the beginning of a string (like grabbing the first few bricks). RIGHT$: Extract characters from the end of a string (like picking up the last few bricks). MID$: Grab a chunk of characters from anywhere in the string (like taking out a specific brick in the middle). Furthermore, you will even have access to two relevant examples: 1. Write a program in QBasic to enter the names of any three students and display the longest one. 2. Write a program in QBasic to input a word/string and display the alternate letters in the capital. [Eg: COMPUTER = cOmPuTeR] Witness the power of library functions in action as we showcase a mini-project that integrates various functions to create a functional QBasic application. This project will serve as inspiration for your programming endeavors. Whether you are a student aiming to excel in your programming coursework or an enthusiast eager to explore the vast world of QBasic, this video is your go-to resource.
