Explain storage classes, memory layout of c?

Question

Accepted Answer

Storage classes in C define the scope and lifetime of variables.

C has four storage classes: auto, register, static, and extern.
Auto variables are local to a block and have automatic storage duration.
Register variables are stored in CPU registers for faster access.
Static variables have a lifetime throughout the program and are initialized only once.
Extern variables are declared in one file and can be accessed in other files.
Memory layout of C includes stack, heap, and data segments.
Stack is used for storing function calls and local variables.
Heap is used for dynamic memory allocation.
Data segment is used for storing global and static variables.
