C/C++ Source Codes

references are very useful to un-pointer variables

//To end with, for people who have to deal with pointers
//yet do not like it, references are very useful to un-pointer variables :
#include <iostream.h>
double *silly_function () // This function returns a pointer to a double
{
static double r = 342;
return &r;
}
void main()
{
double *a;
a = silly_function();
double &b = *a; // Now b IS the double towards which a points !
b += 1; // Great !
b = b * b; // No need to write *a everywhere !
b += 4;
cout << "Content of *a, b, r : " << b << endl;
}
