int main() {

  int myAge = 43;  // Variable declaration

  int* ptr = &myAge;  // Pointer declaration

​

  // Reference: Output the memory address of myAge with the pointer (0x7ffe5367e044)

  printf("%p\n", ptr);

​

  // Dereference: Output the value of myAge with the pointer (43)

  printf("%d\n", *ptr);

  return 0;
