In C++, a variable that has been defined but not initialized may not be use as an ______. (l-value or r-value).
Fill in the blank(s) with the appropriate word(s).
r-value
The value of an uninitialized variable may not be fetched. C++ does not
enforce this. If an uninitialized variable’s value is fetched you get whatever value was left
in the memory location by a previous user. Note that the value is garbage in the
dictionary sense, It is not a random value.
