This is a C++ codelab problem.

The "origin" of the cartesian plane in math is the point where x and y are both zero. Given a variable, origin of type Point-- a structured type with two fields, x and y, both of type double, prepare one or two statements that make this variable's field's values consistent with the mathematical notion of "origin".

Assume two variables p1 and p2 of type POINT, with two fields, x and y, both of type double, have been declared. prepare a statement that reads values for p1 and p2 in that order. Assume that values for x always precede y.
In mathematics, "quadrant I" of the cartesian plane is the part of the plane where x and y are both positive. Given a variable, p that is of type POINT-- a structured type with two fields, x and y, both of type double-- prepare and expression that is true if and only the point represented by p is in "quadrant I".
