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 vertical axis represents the position of the object. For example, if you read the value of the graph below at a particular time you will get the position of the object in meters. Try sliding the dot horizontally on the graph below to choose different times and see how the position changes.
