What is the difference between a pointer anf a memory location?

Question

please help me with my question I'm unable to understand them both and compare them.

Answer 1

When you declare a variable, memory is allocated.
A pointer "points" to a part of memory using address.

px = &x; // px stores x address .

So if the x changes. When you access you pointer by using *.
The value stored in memory changes. (Off course because they reference
the same part of memory)

When x is deleted (Read about scope and local variables)

You still can have access of x values. You just need to access the memory
that your pointer references.

Answer 2

a pointer is the place where the address of your data (in other words where your memory is located) is stored
