🧑💻 Structures in C Programming – Complete Beginner to Advanced Guide with Fully Commented Programs 🚀 Introduction In C programming, arrays allow us to store multiple values of the same data type. But what if we want to store: Student name (string) Roll number (int) Marks (float) All together in a single unit? 👉 That’s where Structures come into the picture. A structure allows us to group different data types under one name. 📌 Real-World Use of Structures Structures are used in: Student Record Systems Employee Databases Banking Applications Inventory Management Systems Operating Systems File Handling If you understand structures properly, you are ready for advanced C programming. 📌 1️⃣ What is a Structure in C? A structure is a user-defined data type that allows grouping variables of different data types under one name. Unlike arrays (same data type), structures can store different types together. 📌 2️⃣ Syntax of Struc...
