    stuck!!!!

    Hi,

    pls give some ideas about this:
    Thanks a lot.......

    1)A function is reading data from text file , that same function is returning 2 values after reading from the file ( so I made inputfile , in the argument list as call by reference (right or wrong)
    if wrong what should be done ......

    funcn defination is :
    Code:
    int  readFromFIle(account database[], ifstream &inputFile)
    { :
       :
        :
     return count ;
    return tempPIN;
    }


    2) when I am calling the above function , in the Main ,how I am suppose to store this 2 variables ??

    Code:
    int Main()
    {
    :
    :
     ??? (variable 1) = readFromFIle( database, inputFile)
     ???(variable2 ) =  readFromFIle( database, inputFile)
    return 0;
    }

    3)I have to use those 2 variables in number of other functions

    Code:
    case 1: NewAccountCreation(database, totalRecord , tempPIN);
    case2 : openExistingAccount(database, totalRecord, tempPIN);
    Are all the methods right?????because I feel my 1st and 2nd part is wrong........

    help!!!!!!!!!

    A function can't return two different variables at the same time. You could pass them by reference and have the function fill them perhaps.


    Code:
    void  readFromFIle(account database[], ifstream &inputFile, int& count, int& tempPIN)
    { :
       :
        :
    count = 6;
    tempPIN=1234;
    }
    
    
    
    int main()
    {
       // other stuff declared
       int pin;
       int count;
       readFromFile(database, inputFile, count, pin);
    
       return 0;
    }
    Prove you can code in C++ or C# at TopCoder, referrer rrenaud
