Question

hey, i’m a noob to c++ (and coding in general)
i’m looking for an easy way to take two doubles (at once) from the keyboard and store them in a struct i’ve created called “Point” and then ultimately store the Point into a vector of Points that’s a member of a class (called “Polygon”).
i know i could do it with a scanf but need to know how to do it with cin.

hope that makes sense.

thanks in advance

Answer 1

You can do:

double d1,d2;
cin>>d1>>d2;

or you can directly read it into your structure variable as:

point p;
cin>>p.x>>p.y;

assuming your structure is defined something like:

struct point {
 double x;
 double y;
}
