Short answer: No.

Long Answer:

In C variable names do not exist after compilation (everything is converted to either memory locations or register locations).

The compiler may potentially assign multiple variables to the same memory/register location if their lifespans of the two objects do not overlap. Thus the concept of variable names at runtime has no meaning (in the context of C)
