* Read some integers into an array, then echo them.
using namespace std;
const int ARRMAX = 100;
/* Read them in. */
int arr[ARRMAX]; /* Array of numbers. */
int sub = 0;
cout << "Enter some integers: " << endl;
while(cin >> arr[sub])
int num = sub;
/* Print them back out again. */
cout << "===============" << endl;
for(int sub = 0; sub < num; ++sub)
cout << arr[sub] << " ";
cout << endl;
Here we simply read in an array and echo the contents.
Notice that we declare the array, but don't have to new.
The size is a constant, which is required.
The size of the array is given in brackets after the array name
(don't put it after the type), and it must be a constant.
Subscripting is the same as in Java, and
the legal subscripts are from zero to the array size less one.
