Let pointers fly!

But before the pointers flying, let's make them point to something.

Firstly, point to some variables (including int, double or char, etc.) after they are defined.

int number_of_students = 99;
int * pn = &number_of_students;

std::cout << "The value of variable `number_of_students` is: " << (*pn) 
    << " or " << number_of_students << std::endl;
std::cout << "The address of variable `number_of_students` is: " << (pn) 
    << " or " << &number_of_students << std::endl;

Secondly, point to some arrays (including arrays of int, double or char, etc.) after they are initialized.

char name[] = "Sherlock Holmes";
char * pc = name;   // or `pc = &name[0]`

std::cout << "The second letter of the name is " << 
    name[1] << " or " <<
    pc[1] << " or " <<
    *(pc+1) << std::endl;

Thirdly, point to some dynamically allocated memories ...
