    Determine which points on graph of X = sqrt(Y) are closest to (0,3)

    Wait so is my answer right or is Mark's answer right? What i did is i solved for y, and i got Y = X^2. and then from there, i used the distance formula. (0,3) were my first points, my second points were (X,Y) then i knew that Y = X^2 so i plugged it into my distance equation, then i squared the...

    Determine which points on graph of X = sqrt(Y) are closest to (0,3)

    Homework Statement Determine which points on graph of X = sqrt(Y) are closest to (0,3). What is the minimum distance between the point(s) found and the graph of x = sqrt(Y) Homework Equations I used the distance formula. The Attempt at a Solution I came up with (sqrt(2) , 2)...

    C/C++ Getline() Help for C++ Class: Assigning Multiple Variables from One Line of Data

    Yeah i figured that out right after i posted that, i tried putting getline before the cin, and it worked like magic. Now the only problem is the converstion. My instructor was talking about something like Covert::ToDouble. and i was trying that but the compiler was giving me bunch of...

    C/C++ Getline() Help for C++ Class: Assigning Multiple Variables from One Line of Data

    Now i have another problem. I did get the string to break apart. But when i was woking in XP, it worked perfectly fine. Now in vista, it doesn't work. I don't know if its an OS problem but this is how i have it set up. cout << "Enter the sales, separated by a comma: "...

    C/C++ Getline() Help for C++ Class: Assigning Multiple Variables from One Line of Data

    well, for that i am only allowed to use static_cast, so i think ill have to do that =/. But thanks for letting me know on the strings thing. But i need to be able to enter all the numbers in one line, and then at the end display them in another line. And i can only use getline. So i can't use...

    C/C++ Getline() Help for C++ Class: Assigning Multiple Variables from One Line of Data

    well, we aren't using strings, we are just using double. Atleast i am, because the problem is that i have to enter 3 sale amounts and 3 month names. Then i need the program to display the total, the average. Then it will display what sale1 = , what sale2= and what sale3 = . So at the start, i...

    C/C++ Getline() Help for C++ Class: Assigning Multiple Variables from One Line of Data

    but my instructor has specifically asked us to use getline() function and that only. I believe its something like getline(sales1,sales2,sales3), and i have tried that, but it just won't work.
