#include <iostream>
using namespace std;

{
	int Minimum = Numbers[0];

	for(int i = 0; i < Count; i++)
		if( Minimum > Numbers[i] )

	return Minimum;

	double Minimum = Numbers[0];

int main()
{
	int Nbrs[] = { 12, 483, 748, 35, 478 };
	int Total = sizeof(Nbrs) / sizeof(int);

	int Minimum = Min(Nbrs, Total);
	cout << "Minimum: " << Minimum << endl;

	return 0;
}

Here is an example of running the program:

Minimum: 12
