 char a;
 char b;

printf("Enter a charater: ");
scanf("%c", &a);
printf("Your input is: %c\n", a);
printf("The address of this charater is: %u\n", &a);

printf("Enter a charater: ");
scanf("%c", &b);
printf("Your input is: %c\n", b);
printf("The address of this charater is: %u\n", &b);

I can only input the first one, it skips the second input, why???

That said, use `%p` for printing pointers. – Sourav Ghosh Apr 12 '17 at 07:46
... which you must manually cast to `void*` when you pass them as arguments – StoryTeller - Unslander Monica Apr 12 '17 at 07:47
Probably `b` is loaded with LF (new line) code. You enter e.g. `Y`, hit enter - first `scanf` gets `Y`, second - LF (new line/enter). Add 2-3 additional `scanf`-s. – i486 Apr 12 '17 at 08:14
