- 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, write 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. Write 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-- write and expression that is true if and only the point represented by p is in "quadrant I".
