    Question new way of doing it

    Code:
     deduction = 0;
          if(deductiontype.compare("Itemized") == 0)
           {
             while(1)
               {
              input>> deditem;
              if(deditem==0)
    
             break;
               deduction =deduction+ deditem;
                }
          }
    im trying to figure out if there a different way to put while(1)
    which equalls true but is there a different way without putting 1 in there

    Code:
    do{ 
    	cin >> ded;
    	deduction+=ded;
    }while ( ded != 0);

    For starters, format your code properly, e.g.,
    Code:
    deduction = 0;
    if (deductiontype.compare("Itemized") == 0)
    {
        while (1)
        {
            input >> deditem;
            if (deditem == 0)
                break;
            deduction = deduction + deditem;
        }
    }
    Now, it is easy to see that you can simplify to:
    Code:
    deduction = 0;
    if (deductiontype.compare("Itemized") == 0)
    {
        while ((input >> deditem) && deditem != 0)
        {
            deduction += deditem;
        }
    }
    Incidentally, if you were just looking to replace the 1, then replace it with true, or you can use for (;;) instead.
    Salem and iMalc like this.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
