When subtracting two pointers in C

Question

I was playing with pointers in order to fully get the concept and then wanted to subtract two pointers expecting the distance between these two addresses or something, but a

Answer 1

The subtraction of 2 pointers give the distance in between the 2 variables. For eg.

//let the address of a is 1000 then of a+1 will be 1004

int a[]={1,2,3};
int *p1=a;
int *p2=a+1;
printf("%u",p2-p1);

The result of this will be 1 not 4. Same here in your case the the location of x and y are consecutive that is why the ans. is 1.
