How to occurrence digits in string function.

Hi everyone.
Actually I'm still new in c++ programming.
I want to create a program so that when a person input "122555abc", the output will be :

Digits Occurrence
1 1
2 2
5 3


Did anyone can help me?
Please...

Well show your atempt so far

Well here is the code to display the numbers in a string without any chars.

Code:

---

for (i = 0; i < message.length(); i++)
     
      if(isdigit(message.at(i)))
      cout << message[i] << endl;

---

This is only a start and is showing you how to loop through the string to search for digits.
