Welcome to Blockchain Tutorial 16 in our Solidity Mastery Series 2025! 🚀 In today’s video, we dive deep into Structs in Solidity — the MOST powerful way to create custom data types inside Smart Contracts. This lecture includes theory + real implementation on Remix IDE 💻 with clear examples for absolute beginners. 🔍 What You Will Learn in This Video: ✅ What are Structs in Solidity? – Custom data type – Group multiple fields together – Similar to objects, classes, JSON, or records – Used in 90% of real-world smart contracts ⭐ Real-World Examples: ✔ Student → name, age, marks ✔ Product → id, price, quantity ✔ Voter → CNIC, voted, candidateID ✔ NFT → owner, metadata, price 🎓 Complete Practical Implementation (Remix IDE) ✔ Creating a Struct (Student) struct Student { string name; uint age; uint marks; } ✔ Storing One Student: – Using student1 – Using constructor-like format – Using set function ✔ Dynamic Array of Structs: – Student[] public students; – Add multiple students – Retrieve student details by index 💡 Why Structs Are So Important: – Used in ERC721 NFTs – Used in DAOs, Voting Systems, Marketplace Orders – Best way to manage large organized data – Extremely flexible and gas-efficient ⭐ Part of Phase 2 in our Blockchain → Solidity → Web3 Roadmap 👉 Don’t just code — build enterprise-level Smart Contracts! 📢 Subscribe to The Techzeen and become a Blockchain Developer in 2025 🔔 🎯 Source Code: https://github.com/farzeen-ali/Blockchain-Solidity 📘 Blockchain Lectures (GitHub Notes): https://github.com/farzeen-ali/Blockchain-Lectures 📺 Blockchain Full Course 2025 (Playlist): https://www.youtube.com/playlist?list=PL5OhSdfH4uDvKfoYd1GRf5KCu7kvgYSw_ 🎓 Cyber Security Full Course 2025: https://www.youtube.com/playlist?list=PL5OhSdfH4uDuCcQ-NZ4lYa3S07FQTFtrY ⚙️ DevOps Tutorial 2025: https://www.youtube.com/playlist?list=PL5OhSdfH4uDsyUM02ZHl2mOYBpihCYsml #BlockchainTutorial #SolidityTutorial #SolidityStructs #StructsInSolidity #SmartContract #RemixIDE #SolidityForBeginners #BlockchainDevelopment #Web3 #Crypto #TheTechzeen #SolidityMastery #BlockchainCourse #CustomDataTypes
