    printf("%d\n", *srank); //the value inside of that memory address. this equals to => *&age. while &age contains the memory address of itself, *&age contains the value inside of that memory address. this is called "dereferencing".

// srank == &*&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*srank < this returns true, hopefully you get the idea
