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.
The x-axis is a horizontal line and the y-axis is a vertical line. I'm sure you've heard that a million tâ¦imes, but here's a trick to help you remember... x is left (try to hear the rhyme) y is high (to the sky) Of course: x goes left or righty goes up and down.
