Memory Management in C: A Deep Dive
Understanding pointers, dynamic allocation, and how to avoid common pitfalls like memory leaks and segmentation faults.
C gives us direct control over memory. That control is powerful, but it also means the programmer is responsible for every allocation, ownership decision, and release.
A useful mental model is to treat every allocation as a resource with one clear owner. The owner may transfer that responsibility, but at any point in the program it should be obvious who must call free.
Tools such as AddressSanitizer and Valgrind make memory bugs easier to find. They work best as part of the normal development loop instead of as a final check before release.
