How do I split an int into its digits?

Question

How can I split an int in c++ to its single numbers? For example, I\'d like to split 23 to 2 and 3.

Answer 1

You can count how many digits you want to print first

#include 
#include 
using namespace std;

int main(){
int number, result, counter=0, zeros;

do{
    cout << "Introduce un numero entero: ";
  cin >> number;

  }while (number < 0);

  // We count how many digits we are going print
  for(int i = number; i > 0; i = i/10)
        counter++;

   while(number > 0){

       zeros = pow(10, counter - 1);

       result = number / zeros;
       number = number % zeros;
       counter--;

       //Muestra resultados
       cout << " " << result;
   }
   cout<

}
