    Code:
    #include <iostream>
    #include <sstream>
    using namespace std;
    
    int main () {
    
      int val;
      string mystr;
      stringstream ss (stringstream::in | stringstream::out);
    
      ss << "120 42 377 6 5 2000";
    
      for (int n=0; n<6; n++)
      {
        ss >> val;
        cout << val*2 << endl;
      }
    
      return 0;
    }

    ummm...

    Now I really feel stupid...I have no clue what that bit of code does. Unless I'm totally wrong, that doesn't convert an int variable to a string. Specifically, I have to change the value 135 (or whatever) minutes into "2:15." I know there has to be an easy way to do this. I wish I could just use java...String.valueOf(int x).

    Oops, sorry about that, it's doing string to int. So you want int to string?

    PHP Code:
    #include <stringstream>
    #include <iostream>
    #include <string>
    using namespace std;

    string itos(int i)    // convert int to string
    {
        
    stringstream s;
        
    << i;    // sent i to the stringstream
        
    return s.str();
    }        
    // return the contents of the stream
             // converted to a string

    int main()
    {
        
    int i 127;
        
    string ss itos(i); // Our function

        
    cout << ss << endl// Print it

    Code:
    #include <iostream.h>
    #include <stdlib.h>
    
    int main()
    {
        int num = 15;
        char string[10];
        itoa(num, string, 10);
    
        return 0;
    }
