How can we directly save users input at some memory address in c++?

Question

If user enter a value we usually save it using some variable and also access it using that variable.
eg. int a; // declaration
cin>>a;. // assigning value
cout>>a; // accessing value

here this variable a has some memory address and we can also access it using pointer..

but what if we don't like to create so much of variable in a program?

I would like to save users input directly to a memory address..and not to any variable..!

please explain me in detail how to do it?

Do you know assembler? In C++ you can use assembler code using _asm { put here assembler code}. In assembler you can access directly CPU registers. Every variable you create is saved in this registers.

You need a variable to access the content of a memory location.
