A constant is a variable that does not change. The correct term is constant variable.
Constant data and constant functions.
A constant object is one that, once initialized, never changes value.
c is any constant value
Pass by value, constant value, reference and constant reference. Pass by value is the default in C++ (pass by reference is the default in Java).
The equilibrium constant for the reaction C + O2 -> CO is Kc = [CO]/([C][O2]), where the square brackets denote molar concentrations.
a named constant is pretty much the same thing as a literal constant, except it is a name. both cannot change. literal constants are numbers, named constants are words. tada!
If by permanent you mean constant, you cannot change something that is constant, therefore you cannot add to it (letters or otherwise). It has to be variable. Constant and variable are mutually exclusive terms.
Yes. If n is odd, then n + c where c is an even constant will be odd. n + d where d is an odd constant will be even.
3x + y = c where c is any constant number of your choice.

The "+ C" added in integration represents the constant of integration, which accounts for the fact that the process of integration determines a family of functions that differ only by a constant. Since the derivative of a constant is zero, any constant value could have been present in the original function before differentiation. Therefore, including "+ C" ensures that all potential antiderivatives are represented.
