Note: C, C#, D, D#, E, F, F#, G, G#, A, A#, B Pitch Range: L (low), M (middle), H (high) Lasting Time: specifies how long a note lasts. C, D, E, F, G, A, B can also be labeled as 1, 2, 3, 4, 5, 6, 7. (C# as 1#). • TEXT 10 TEXT “HELLO”, x, y, size (x,y): position of the string “HELLO”. • CIRCLE 10 CIRCLE x, y, radius (x,y): the center of the circle. • RECTANGLE 10 RECT x, y, width, height (x,y): top-left point of the rectangle. • LINE 10 LINE x1, y1, x2, y2 (x1,y1): the starting point of the line. (x2,y2): the ending point of the line. • POINT 10 POINT x, y (x,y): the position of the point. • CLR: clear the edit window. • CLS: clear the graph window. • DELAY 10 DELAY 0.5 0.5:lasting time in seconds This function is used to suspend execution of a program for a particular time. • CURVE 10 CURVE x, y, radius, 0, PI 0: starting angle PI: ending angle The curve draws clockwise with center (x,y). • Mathematical Functions: SIN(X), COS(X), TAN(X), COT(X), ASIN(X), ACOS(X), ATAN(X), SINH(X), COSH(X), TANH(X), ASINH(X), ACOSH(X), ATANH(X). SQR(X): square root of x. ABS(X): absolute value of x. FCT(X): x factorial. LOG(X): natural logarithm of x. LOG10(X): base-10 logarithm of x. LOG2(X) :base-2 logarithm of x. EXP(X): base-e exponential of x. ERF(X): the error function of x. ERFC(X): the complementary error function of x. ROUND(X) :integral nearest to x. CEIL(X): the smallest integral that is not less than x. FLOOR(X): the largest integral that is not greater than x. TGAMMA(X): the gamma function of x. LGAMMA(X): the natural logarithm of the absolute value of the gamma function of x. • Reserved Variables: INKEY : once a key is pressed, the value of INKEY changes. RND : a random number. PI : π • Some Tips: 1. Undo & Redo typing on iPhone with a shake. 2. Copy an Emoji or some character from other places (like Notes), then paste them on the edit window. 3. Exponentiation is expressed as X^Y.

Object-Oriented Programming Languages - Learn OOP Programming Pro 2024 Languages Java, JavaScript, Python, C++, Scala, PHP, Ruby, C, C#, Dart, Cobol, Elixir, Fortran, Go, Kotlin, Lisp, Matlab, Perl, R Programming, Swift, and much more. This is a complete Object-oriented programming languages list for learning [OOP]. In this app, We are going to share free oop programming languages you can take to learn OOP basics to advance or improve your object-oriented programming skills. You can choose your favorite. This oop programming app will help you to focus on object-oriented programming rather than on programming language and its syntax. The OOP or Object Oriented Programming is a paradigm that allows you to write a program by modeling real-world things in terms of class and object. It not only make representing a real-world thing in the programming world easier but also allows you to manage the complexity of your program. Even though there are several programming paradigms e.g. procedural and functional, most of the code we write today is object-oriented and some of the most of popular programming languages are object-oriented e.g. Java, Python, PHP, and JavaScript all supported object-oriented programming. Most of us learned object-oriented programming while learning a programming language. learning Java or Python but that time our focus mostly remain on programming language rather than truly understanding OOP concepts. That’s why many programmers end up knowing how to declare a class or instantiate an object rather than understanding the purpose of class and object and how to design one. App Features 1. You will learn how to use these object-oriented programming concepts in code examples, discover how these concepts are used in real-world applications that require user input and understand the benefits of mastering these concepts in Java. 2. You also will learn about the four pillars that hold together the object-oriented programming, which are: • Abstraction • Encapsulation • Polymorphism • Inheritance 3. This app covers all of them in good detail with some real-world examples. At the end of this app, you will be able to write your own object-oriented programs in Python! 4. This app will lay the foundations of Object-Oriented Programming (OOP) in your mind, allowing you to progress to more complex, systematic and cleaner Programming methods. 5. The app is aimed at students who have at least some coding experience, preferably with C# (but Java or any other similar language is also acceptable). 6. After that, you are introduced to advanced topics before you can use everything you’ve learned to create a functional website with Object-Oriented Using JavaScript cool features. 7. This is a great app to learn object-oriented design principles, which is also an important part of learning Object-oriented programming. 8. This app introduces foundational principles of creating a well-crafted code and is appropriate for anyone hoping to improve as a developer. 9. The app uses Java Programming language. So if you want to learn object-oriented programming using Java, this is the best app for you. 10. This is an awesome app to learn Object-Oriented Programming, one of the leading online learning app. 11. it is also free-to-learn, which means you can join it for free but you need to pay if you need our pro version. This means its completely free if you just want to learn OOP with Java and some other languages.
