Click to edit Master title style 3 High Level Language • It hides computer's inner working complexity. • It is Simple as English. • It’s simplification allows programmers to express their ideas in Code. 3 In programming, ‘High-level language' is a type of programming language designed for easy human understanding. High-level programming languages are like Python, JavaScript, Java, C#, Ruby, and more. People use them in web development, data science, mobile apps, and science stuff.

Computer Language Paradigms Procedural Programming ❑ C ❑ PHP ❑ Fortran ❑ Rust ❑ COBOL ❑ MATLAB Functional Programming ❑ Ruby ❑ Swift ❑ TypeScript ❑ Julia ❑ JavaScript Object-Oriented Programming (OOP) ❑ Java ❑ Kotlin ❑ Python ❑ C++ ❑ PHP ❑ C#

Pre-Processing Compiling Assembling Linking It deals with things like #include and #define commands. It brings in header files code. Then Compiler convert preprocessed code into Assembly Language. Then Assembler changes assembly code into machine code, designed for the particular computer. Then multiple code files are linked into a single program, by linking libraries code.

But, it doesn't tell you how the dish is prepared (the code inside the method). 9 An interface is a set of rules that a class agrees, to perform specific tasks (functions). Interface-Based Programming For programming using interface, Languages like Java, C# has type reference “Interface”. While in Other (OOP) Languages like: C++, Python etc. It is done by Abstract Class & Pure Virtual Function.

Click to edit Master title style 10 Interface in OOP Language (C++) 10 • Parent class is an abstract class because it contains a pure virtual function show(). • Child1 & Child2 Inherits Parent, They provide their own code for show() function. • Later, Create objects of both Child1 and Child2 and call their show() functions. This ensure principle of defining interface (in this case, show()) in an abstract class and having derived classes implement that interface.
- 11. Click to edit Master title style 11 Interface in Java 11 • Printable defines Interface with function print(). • Class1 & Class2 Implement their code for print() function. • Later, Create objects of both Class1 and Class2 and call their print() functions. This code shows how in Java, various classes can implement interface. So, They can define unique behaviors for a common function.

Like: English etc. • Paradigm is a style to write organized code. • Compiling is process of converting human program into machine understandable format. Compiler is used to does this task • Compiling is 4 step process: Preprocessing, Compiling, Assembling & Linking. • Interface is set of functions that a class can perform. • In languages like: Java & C#, Interface is type reference. While in other languages Abstract Class & Pure Virtual Function is used.
