#Include <iostream> #include <string> using namespace std; int main() { int num =

123456789;

string str = to_string(num);
int l = str.length();
for(int i = 0; i < l; i++){
cout << stoi(str[i]) << " " <<endl;
}
return 0;
} - почему я получаю ошибку: test.cpp: In function ‘int main()’:
test.cpp:13:24: error: no matching function for call to ‘stoi(__gnu_cxx::__alloc_traits<std::allocator<char>, char>::value_type&)’
13 | cout << stoi(str[i]) << " " <<endl;
