Pointers

Pointers are the heart of C, the feature that makes it powerful and the one that makes it dangerous. A pointer is just a variable that holds a memory address — but that simple idea is how C functions modify their callers, how arrays and strings work, how dynamic memory is managed, and how data structures are built. Everything hard and everything essential in C runs through pointers.

Pointers and Addressability

What a Go pointer actually is, why there's no pointer arithmetic, `new(T)` versus `&T{}`, the addressability rules that decide what `&` will even compile against, and when reaching for a pointer helps versus when it just adds indirection and GC pressure.
