Question

I am trying to understand this whole pointer and dereference thing in C. I almost got it, but bumped into pretty simple code, which result I don’t understand:

char *ptr = "Characters";
char val = *ptr;
char *chrptr = &val;
printf("Value under character pointer is: %p / %c\n", &val, val);
printf("Dereferenced character pointer: %p\n", chrptr);
printf("Array pointer: %p\n", ptr);

Now, as I understood before execution, ptr == chrptr == &val, but in reality ptr != chrptr == &val. Why is this?

Answer 1

char *ptr = "Characters"; // returns a pointer to 'C'
char val = *ptr; // dereferences the pointer to 'C' and copies 'C' into val

val has its own memory location, so the address of val will be different

 char *chrptr = &val; //chptr points to val. A different memory location.
