make it a vector of ints and subtract the value of '0' to get the numbers

// Example program
#include <iostream>
using std::cout;

#include <string>
using std::string;

#include <vector>
using std::vector;

int main()
{
    string digits("432234123");
    vector<int> v(digits.begin(), digits.end());
    
    for(auto& i : v)
        i -= '0'; // make digits to numbers
    for(const auto& i : v)
        std::cout << i << '\n'; // print digits
}
