an important programme on pointers

//If you are used at pointers in C and wonder how exactly the program
//above works, here is how the C++ compiler translates

#include <iostream.h>
void change (double *r, double s)
{
*r = 100;
s = 200;
}
void main ()
{
double k, m;
k = 3;
m = 4;
change (&k, m);
cout << k << ", " << m << endl; // Displays 100, 4.
}
