Struct in Header File Example

Demonstrates defining a struct in a separate .h file and using it in main.cpp.

Files

File	Purpose
Student.h	Struct definition (the "blueprint")
main.cpp	Uses the struct

Key Concepts

1. Header guards (#ifndef, #define, #endif) prevent multiple inclusion
2. Include with quotes for local headers: #include "Student.h"
3. Initializer list must match struct member order: { id, name, gpa }

Compile & Run

g++ main.cpp -o main
./main

Note: You don't compile .h files directly — they're included into .cpp files.
