You should use %p for addresses.

Every C programmer should initialize the variable he uses.
Try

C

#include <stdio.h>
int main()
{
  char l = 'F';
  char a = l; // a = 'F'
  char * b  = &a; // b is 'address of' a

  printf("the address of a is %p\n",&a);
  printf("the address of a is %p\n",b);
  printf("the value  of a is %c\n",a);
  printf("the value  of a is %c\n",*(&a));

  return 0;
}
