A value that does not change is a constant.
"Constant" means that something doesn't change.

A constant that does not change!
A "constant"
Constant is a quantity that does not change.
You can determine if a rate of change is constant, by taking the instantaneous rate of change at multiple points - if they are all equal to each other, it can be assumed that the rate of change is constant. Alternatively, you can differentiate the function (if there is an associated function) - if this comes to a constant i.e. a number, then the rate of change is constant.
"Slope" can be thought of as rate of change - and a constant doesn't change.
A linear relationship.
The differentiation of a constant is zero because a constant value does not change with respect to the variable being differentiated. The derivative measures the rate of change of a function, and since a constant has no change, its derivative is zero.
1. pointer to a constant means you can not change what the pointer points to 2. constant pointer means you can not change the pointer.
It means something that doesn't change, like a number.
