Stack vs Heap Peek

I poke around memory addresses to see what’s happening with stack variables and heap allocations. No deep systems programming here, just me being curious.

What it does

• main sets up a number on the stack, grabs its address (the “base”).
• show:
  • Prints the value.
  • Shows the stack address where it lives.
  • Calculates how far it is (in bytes) from the base address.
• heap_example:
  • Allocates a number on the heap using Box.
  • Turns it into a raw pointer.
  • Prints the value and address (unsafe block because raw pointers are spicey).

Sample output (yours will vary)
