Demonstrate register variables
#include <iostream>
using namespace std;
int f(int nums[], int n);
int main()
{
int vals[] = { 1, 2, 3, 4, 5 };
int result;
result = f(vals, 5);
cout << "Summation is " << result << "\n";
return 0;
}
int f(int nums[], int n)
{
register int i;
register int sum = 0;
for(i = 0; i < n; i++)
sum = sum + nums[i];
return sum;
}Summation is 15
