/*
* Read some integers into an array, then echo them.

#include <iostream>
using namespace std;
// It's usual to give a name to array sizes.
const int ARRMAX = 100;
int main()
{
// We create native array and fill it with input values up to
// the size of the array. If there are more input values, they
// are ignored.
int arr[ARRMAX];
int sub = 0;
cout << "Enter some integers: " << endl;
while(sub < ARRMAX && cin >> arr[sub]) {
++sub;
}
int num = sub;
// Print them back out again.
cout << "===============" << endl;
for(int sub = 0; sub < num; ++sub) {
cout << arr[sub] << " ";
}
cout << endl;
}
Same thing again, this time being carful not to take the
array out of bounds. This is why the size is given a name:
the native array has no size method.
