Why shouldn't the compiler at least flag this with a warning?  If not
at parse time, then at least at load time.  Aren't the function names
munged to include parameter types?

#include <stream.h>

int data[10] = { 4, 7, 12, 5, 0, 3, 87, 445, -2, 10 };

main()
{
	int j, i;
	void swapit(int i, int j);	// <<< Non-reference parameters

	for (j = 0; j < 10; j++) {
		for (i=j+1; i < 10; i++) {
			if (data[i] < data[j])
				swapit(data[i],data[j]);
		}
	}

	for (i = 0; i < 10; i++) cout << data[i] << " ";
	cout << "\n";
}

//          vvvvvv Reference parameters
void swapit(int& i, int& j) { int temp = i; i = j; j = temp; }
