Using Pointers to Return More Than One Value

Question:
Can you show me an example that demonstrates how to use pointers to return more than one variable?

Answer:
A function cannot return more than one value. However, you can return a pointer to struct containing a set of values:


struct S
{
int a;
int b;
};
S* func()
{
  S * ps = new S;
  ps->a = 0;
  ps->b = 1;
  return ps;
}
You can also return a pointer to an array of variables:

int * func()
{
 int * p = new int[5];
 return p; 
}
