Making vectors

Now we're going to make some vectors. Every time somebody clicks on the Button control, you get to make a vector. So, between a set of curly braces under the line that begins with protected void Button1_Click..., enter the following:

Vector vec1 = new Vector(1, 2);

So (1, 2) refers to the x and y coordinates of the vector. Repeat this a couple of times as follows, renaming the vector vec2, vec3, and so on. Also, change the x and y coordinates as shown here so that they're not all the same; otherwise, it's going to get confusing:

Vector vec2 = new Vector(3, 4);Vector vec3 = new Vector(5, 6);

Imagine that you want to add these vectors together. For example, you want to add the first vector to the second vector and then the third ...
