R Values And L Values

These two different types of values explains a lot of what happens and why things are the way they are in C++

L-Values

L-values are values that are on the left side of the equation, they are values that are stored at a location in memory.

R-Values

R-values are values that are read-only and they are temporary, they are the results of expressions. Ex.

5 // <-- r-value
(10 % 2) // <-- r-value
