Hi, here is step by step of how I try to understand C program running on baremetal. First try to understand of byte addressable, char, int and various variable size. Follow up by heap, stack and the memory allocation. Memory Allocation - https://x.com/chessman786/status/1859054892293517531?s=46 https://martinlwx.github.io/en/what-is-the-heap-and-stack/#fnref:2 Youtube CoreDumped - Why is STACK so fast? and Why is HEAP so SLOW?

4. Stack/buffer overflow
