1-D arrays with functions (recursive-sum-evens)
write a recursive function that gets an integer array and its number of
elements. the function should return the sum of even elements in the array.
(2 KD)
enter 10 integers: 2 1 5 7 8 10 3 4 9 6
sum evens is: 30
# include <iostream>
using namespace std;
int main ( )
{
int x [10], i, sum;
cout << "enter 10 integers: ";
for (i = 0; i <= 9; i++)
cin >> x [i];
sum = sum_evens (x, 10);
cout << "sum evens is: " << sum << end l;
return 0;
}
