Console closing after turning back to attack()

[Private200]

Hey. It's me again. I'm trying to make a simulated battle, but to do so I have to
use some voids which I learned some time before. I don't know what's happening, but after I get/make the first attack and it tells me what to do next, console closes. This is the code I got

void attack()
{
     int dmg = rand()%30;
     int dmgb = rand()%30;
     healtha = healtha - dmg;
     cout << "\n\nYou hitted your opponent, dealing him " << dmg << " damage";
     healthb = healthb - dmgb;
     cout << "\n\nOpponent hitted you back, dealing " << dmgb << " damage";
     cout << "\n\nOpponent health: " << healtha << ". Your health: " << healthb << ".\n";
     
}
void get()
{
     int prob = rand()%5;
     if(healtha > 0 && healtha < 21)
     {
          if(x > 0)
          {
                cout << "You threw a pokeball, in order to catch the opponent pokemon!";
                if(prob == 0)
                {
                    cout << "______";
                    cout << "\nFailure! You didn't caugh any pokemon and lost a pokeball instead!\n\n";
                    x = x-1;
                    save(x, y, z);
                }
                else if(prob ==1)
                {   
                    cout << "______";
                    cout << "\nSuceed! You caught a pokemon!\n\n";
                    save(x, y, z);
                    y = y+1;
                    x = x-1;
                }
                else if(prob == 2)
                {
                    cout << "______";
                    cout << "\nFailure! You didn't caugh any pokemon and lost a pokeball instead!\n\n";
                    x = x-1;
                    save(x, y, z);
                }
                else if(prob == 3)
                {
                   cout << "______";
                   cout << "\nFailure! You didn't caugh any pokemon and lost a pokeball instead!\n\n";
                   x = x-1;
                   save(x, y, z);
                }
                else if(prob == 4)
                {
                   cout << "______";
                   cout << "\nFailure! You didn't caugh any pokemon and lost a pokeball instead!\n\n";

                }
                else if(prob == 5)
                {

                }
          }
          else

              cout << "\n\n You don't have enough pokeballs to catch this pokemon.";
          }
     }
                
}
void flee()

     if(healthb > 49)
     {
                cout << "You fled away successfully.";
     }
     else { cout << "Opponent didn't let you flee away."; attack(); }
}

     string o;
     int dmg = rand()%30;
     int dmgb = rand()%30;

Thanks for any answer that you might give me!

You need a loop, like so:

void battle()
{
     string o;
     int dmg = rand()%30;
     int dmgb = rand()%30;
     healtha = 100;
     healthb = 100;
     cout << "\nBattle has started. You will now be able to attack, catch the pokemon or flee away.\n\n";
do // Note
{
     cout << "Opponent health: " << healtha << ". Your health: " << healthb << ".\n";
     cout << "What do you want to do next? Attack (a), catch (c - opponent health must be at least 20 or less) or flee (f)?";
     cin >> o;
     if(o == "a" || o == "A")
     {
          attack();
          if(healtha < 1) 
          {
               healtha = 0;
               cout << "\n\nYou killed the opponent, winning the match.\n\n";
          }
          else
          {
               cout << "What do you want to do next? Attack (a), catch (c) or flee (f)?";
               cin >> o;
               if(o == "a" || o == "A")
               {
                    attack();
               }
               else if(o == "c" || o == "C")
               {
                    get();
               }
               else if(o == "f" || o == "F")
               {
                    flee();
               }
          }
     }
     else if(o == "c" || o == "C")
     {
          get();
     }
     else if(o == "f" || o == "F")
     {
          flee();
     }
}
while((healtha > 0) && (healthb > 0)); // Note
}
