Let's consider a code example showing what would be allowed (or not) using different levels of inheritance: 1  class BaseClass {}; void freeStandingFunction(BaseClass* b); class DerivedProtected : protected BaseClass { DerivedProtected() { freeStandingFunction(this); // Allowed } };
Definition of Horizontal Axis. Horizontal means flat or level. Horizontal axis is the x-axis on a graph. The blue number line in the figure below is the x-axis, the horizontal axis.
1 This axis is the main horizontal line of the rectangular axis or Cartesian plane. 2  The y-value tells how the point moves either up or down along the y-axis. 3  This axis is the main vertical line of the rectangular axis or Cartesian plane. point in a plane contains two components where order matters! It comes in the form (x,y) where x comes first, and y comes second. 1  The x-value tells how the point moves either to the right or left along the x-axis.
