Where does global, static, and local, register variables, free memory and C Program instructions get stored?

Question :

Where does global, static, and local, register variables, free memory and C Program instructions get stored?

Global: Wherever the linker puts them. Typically the ―BSS segment‖ on many platforms.

Static: Again, wherever the linker puts them. Often, they‘re intermixed with the globals. The only difference between globals and statics is whether the linker will resolve the symbols across compilation units.

Local: Typically on the stack, unless the variable gets register allocated and never spills.

Register: Nowadays, these are equivalent to ―Local‖ variables. They live on the stack unless they get register-allocated.
