Memory Allocator
Implement your own memory allocator from scratch in modern C++ with zero external dependencies. You request memory from the operating system, carve it into blocks, track free and used regions, and implement malloc and free yourself with coalescing and splitting. A low-level project that demystifies dynamic memory.

What You'll Build
A working general-purpose allocator with your own malloc, free, and realloc that manages a heap, splits and coalesces blocks, and drops into real programs.
Learning Objectives
- Request raw memory from the OS with mmap or sbrk
- Design block headers to track size and allocation status
- Implement allocation with a free list and a fit strategy
- Split oversized blocks and coalesce adjacent free blocks
- Handle alignment requirements for returned pointers
- Wrap the allocator behind a standard-compatible interface
- Detect and guard against common corruption with sentinels
