Question

c++ program

Write a recursive function that computes and returns the product of the first n >=1 real numbers in an array.

Answer 1

#include <iostream>

using namespace std;

int product(int arr[], int n) {
    if (n == 0) {
        return 1;
    } else {
        return arr[n-1] * product(arr, n-1);
    }
}

int main() {
    int arr[] = {4, 9, 1, 3, 2, 7};
    cout << product(arr, 6) << endl;    // prints 4*9*1*3*2*7 = 1512
    return 0;
}
