Where are volatile variables stored? [duplicate]

Question

Can I know where the volatile variable is getting stored in the memory?

1. If i declare globally means where does it get stored in the memory?

   volatile int a =10;
   int main()
   {
       printf("Global A value=%d",a);
       return 0;
   }
   

2. If i declare locally inside the function means where does it get stored in the memory?

   int main()
   {
       volatile int a =10;
       printf("Local A value=%d",a);
       return 0;
   }
   

Does it get stored in Stack / RAM / Data segment ?

Please clarify my doubts.

Answer 1

volatile just tells the compiler it can't cache the value of the variable in a register—it doesn't change where it gets allocated.
