What will you learn in An In-Depth Understanding of Memory and Pointers in C Course
Master C’s memory model: stack vs. heap vs. static segments and variable lifetimes
Confidently declare and use pointers, including dereferencing, pointer arithmetic, and safety checks
Allocate and manage dynamic memory with
malloc,calloc,realloc, and properfreeusage
Leverage advanced pointer constructs: function pointers, pointer-to-pointer, and custom allocators
Debug and prevent common memory issues: dangling pointers, leaks, buffer overflows, and alignment pitfalls
