Small question about input streams...

Right, I know this is for a trivial program but I'm trying to improve my problem solving skills by making a program that will calculate the average of any amount of numbers you enter, and I plan to do this using Vectors.

The question is, I know how to put things into vectors, but I'm not sure about multiple items. Here's what I was thinking:

Code:

---

cin >> Avg1 >> Avg2 >> Avg3;

double x;

while (cin >> x)
{
        Average.pushback(x);
}

---

I know why cin >> x works, but will it put all 3 of the values into the vector, or just the latest one I've added (Avg3)?

If what I've said is hard to understand, can cin hold multiple values ready to used?

You are using a loop, so it will put values into the vector until EOF is reached (e.g., the user enters CTRL + Z or CTRL + D).

That's exactly how I was going to do it, with an End Of File, I just wasn't sure if I could read multiple values into a single variable. Thanks for clearing this up for me :)
