int main() {

  int myAge = 43;  // An int variable

  int* ptr = &myAge;  // A pointer variable, with the name ptr, that stores the address of myAge

​

  // Output the value of myAge (43)

  printf("%d\n", myAge);

​

  // Output the memory address of myAge (0x7ffe5367e044)

  printf("%p\n", &myAge);

​

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

  printf("%p\n", ptr);

​

  return 0;

}
