Inst.

1. Implement the findRing() function w/ the ff. details
2. Return type int
3. Name findRing
4. Parameters
5. int* - rings array
6. int - array size of rings
7. int - ring she wants
8. Return value - the index of the ring in the array of rings.

Given code

#include <iostream>

using namespace std;

// TODO: Declare findRing()

int main(void) {

  int rings[10];

  for(int i = 0; i < 10; i++) {

    cout << "Enter option #" << i + 1 << ": ";

    cin >> rings[i];

  }

  int wantedRing;

  cout << "Enter the ring she wants: ";

  cin >> wantedRing;

  cout << endl << "Ring " << wantedRing << " is found at option " << findRing(rings, 10, wantedRing) + 1 << "!";

  return 0;

}

// TODO: Define findRing()

Ex
