String to Int converstion using <sstream>

Dev-C++ debugger stops at this section o' code.. I am wondering if my attempt at using the istringstream object is anywhere close to correct.. and maybe a few pointers on how to use it correctly:

Code:

int tempint = 0,
    qnty = 0;             
     
     for(int i=0, end=lotarray.size(); i<end; i++)
     { 
        istringstream myStream(lotarray[i].numbers);  //lotarray[i].numbers is a string that would look like this:  "9,13,4,11,45,27"      
        
        for(int j=0; j<5; j++)
        {
           myStream >> tempint;
           game_nos.push_back(tempint);
        }
        
        myStream >> tempint;
        pballs.push_back(tempint);  
     }

the game object:

Code:

struct game
{
    string date;
    string numbers;

   friend istream& operator>> (istream& ins,  game& target);   
   friend ostream& operator<< (ostream& outs, game& target);
};

the lotarray object:

Code:

vector<game> lotarray;

complete code is available upon request.. my program compiles, so I don't have any compiler errors.. just seems to stop working when it reaches the above code.

Maybe if you separated your numbers with whitespace?

Yes, I suspect the myStream >> tempint is waiting for more data, thus the hang. The first >> operation is reading the whole string into the stream. Use your debugger and watch it.

You could use getline(myStream,tempint,',') to do this without changing the existing lotarray format.

Also, it appears there are 6 numbers, not 5, so your j loop is dropping one off.

There is additional read after the loop
