Problems with function parameter...

Aug 7th, 2009

I'm juz wondering how do I send a single value to a 8-parameter function...

void enterdata1(int &row1col2)
{
    cout<<"Please enter the number for Row 1-Columm 2"<<endl;
    cin>>row1col2;
    if(row1col2 != 1 && row1col2 != 2&& row1col2 != 3 && row1col2 != 4)
    {
                cout<<"Please enter the correct number (Which is between 1-4)"<<endl;
                cin>>row1col2;
    }
     displaydata(row1col2);
}
 
void displaydata( int &row1col1,int &row1col2,int &row1col3,int &row1col4,int &row2col1,
                  int &row2col2,int &row2col3,int &row2col4,int &row3col1,int &row3col2,
                  int &row3col3,int &row3col4,int &row4col1,int &row4col2,int &row4col3,
                  int &row4col4)
{

     displaydata(row1col2);
}

void displaydata( int &row1col1,int &row1col2,int &row1col3,int &row1col4,int &row2col1,
                  int &row2col2,int &row2col3,int &row2col4,int &row3col1,int &row3col2,
                  int &row3col3,int &row3col4,int &row4col1,int &row4col2,int &row4col3,

Re: Problems with function parameter...

If you only pass one parameter to the function then what's the program supposed to do with the other 8?? Besides, regardless of the name of the variable that you're sending the data will go to the first parameter in the function. So basically you're sending row1col2 to row1col1... which is not what you want to do. Why can't you pass all 8 parameters at the same time? You can have the function enterdata1() just return the value to main and have main call the displaydata() function with all 8 parameters.
