Pointer Fundamentals and Memory Model

Explain how memory is organized in C programs (stack, heap, data segment, code segment).

Describe what a pointer variable stores and how it differs from regular variables.

Use the address-of operator (&) to obtain memory addresses of variables.

Use the dereference operator (*) to access and modify values through pointers.

Declare and initialize pointers correctly for different data types.

Explain pointer size and its relationship to system architecture (32-bit vs 64-bit).

Trace pointer operations through memory diagrams for simple programs.
