Intro to Programming Lang.pptx
- 1. Introduction to Programming Languages Technical Training Sessions July 29, 2022
- 2. What is a Programming Language? • Consist of Instructions. • Set of rules that converts strings, or graphical program elements in the case of visual programming languages, to various kinds of machine code output. • Usually split into the two components of Syntax and Semantics.
- 3. Types of Programming Languages • World Wide Web Languages • E.g., HTML, XML. • Front-End Languages • Code for Visual Effects. E.g., HTML, CSS, JavaScript. • Procedural Languages • Data Viewing range of Codes. E.g., C/C++, Java, JavaScript. • Machine Languages • Made of Binary Code. E.g., Fortan. • Assembly Languages • Similar to Machine Language with short mnemonic codes. E.g., Turbo Pascal. • Scripting Languages • Perl, PHP, JavaScript, Python • ….
- 4. How its different? • Programming Language • Set of instructions for communicating with computers and execute logics. • Compiled, Load & Run. • Self-executable. • Low Level Language • High Execution Time • Stronger in data and control abstraction. • High maintenance costs. • Designed to make full-fledged software development easier. • Scripting Language • Used to automate the execution of operations in a runtime environment. • Parsed, interpreted, Executed. • Requires a host. • High Level Language • Low Execution Time • Emphasize on extensibility and richness of expressions • Low maintenance cost • Assist programming languages and make coding easier and faster.
- 5. Usage of Programming Language!!!
- 6. How I will learn? • Core Concepts • Operating Systems (Mandatory) • Data Structures & Algorithms (Mandatory) • RDBMS (Optional) • Networking (Optional) • ???? (Important!) • Understand Implementation • Interpretation • Compilation
- 7. Where I can find material? • Pick up problems • Real-World Problems • Parking Mgmt System • Subscription Mgmt • Practice • Logic Programs • Tools • Cram when required • Refer Websites • Stackoverflow • GeeksforGeeks
- 8. How I will implement? • Understanding Requirements - • Problem Statement • Understanding Constraints - • Performance/ Scope • Time • Money • Understanding Resources – • Availability/ Limitations • Tools & Technologies
- 9. Unable to learn so many languages!! Language is just a syntax Focus on Core Logic Understand the 3 Fs (Feasibility, Functionality, Flow) Quality Assurance Tools Generalization Specialization Practice Writing Pseudo Code
- 10. Something more… • How I assure it’s working well? • Step-By-Step Testing • Covering all corner cases • Benchmarking • I can’t find what’s the issue? • Ghosh, I should have put logging into it • What is this NFRs!!!
- 12. Thank you
Editor's Notes
- Syntax – Form / Format (compilation/ interpretation error) – what is this Format? Semantics – Logic (runtime error) Bytecode – machine code
- XML is standard set by WWW (w3
- ???? – Design Patterns / Programming Principles
- Step by step testing – Simple testing Benchmarking – Penetration testing, Vulnerability testing, Load/Performance Testing
