How can I modify my C++ code to compute the sum of all numbers that are divisible by 3 or 5, and also identify the index positions of those numbers within the original string and include them in the final output?
Here's the current C++ code I have:
#include <iostream>
#include <string>
using namespace std;
int main() {
  string input;
  cout << "Enter a string of numbers: ";
  cin >> input;
  int sum = 0;
  string output = "";
  for (int i = 0; i < input.length(); i++) {
    int num = input[i] - '0';
    if (num % 3 == 0 || num % 5 == 0) {
      sum += num;
      output += to_string(i) + " ";
    }
  }
  cout << "Sum of divisible numbers: " << sum << endl;
  cout << "Index positions: " << output << endl;
  return 0;
}

your code looks good, but you need a minor change to include the original numbers that are divisible by 3 or 5 in the final output, alongside their index positions. here's the modified version of your code:

```cpp
#include <iostream>
#include <string>
using namespace std;

int main() {
  string input;
  cout << "enter a string of numbers: ";
  cin >> input;
  int sum = 0;
  string output = "";

  for (int i = 0; i < input.length(); i++) {
    int num = input[i] - '0';
    if (num % 3 == 0 || num % 5 == 0) {
      sum += num;
      output += to_string(num) + "(" + to_string(i) + ") "; // include the number and its index position in the output
    }
  }
  cout << "sum of divisible numbers: " << sum << endl;
  cout << "numbers and their index positions: " << output << endl;
  
  return 0;
}
```

now, when you run the program, it will display the sum of all numbers that are divisible by 3 or 5, as well as the original numbers and their index positions within the input string.
