Ccpp Structs in C Cpp
A struct bundles several related variables (of possibly different types) into one named type — e.g. a Student has a name, a roll number and marks. This is how C models real-world entities before the language had objects. You access members with the dot operator: s.marks.
When you have a pointer to a struct, use the arrow operator -> instead of dot: p->marks is shorthand for (*p).marks. Passing large structs by pointer avoids copying the whole thing and lets the function modify the original.
A typedef gives a struct a short alias so you can write `Student s;` instead of `struct Student s;`. Structs are the direct ancestor of C++ classes — a class is essentially a struct that can also contain functions and access control.
