* Read some integers into an array, then echo them, using pointers.
using namespace std;
const int ARRMAX = 100;
/* Read them in. Use an body-less loop which increments in the test. */
int arr[ARRMAX]; /* Array of numbers. */
int *scan = arr;
cout << "Enter some integers: " << endl;
while(cin >> *scan++);
int *end = scan - 1; // scan is incremented on fail.
/* Print them back out again. */
cout << "===============" << endl;
for(scan = arr; scan < end;)
cout << *scan++ << " ";
cout << endl;
This uses fancier increments. Note that the increment is
higher precedence, so *scan++ means *(scan++).
