Why storing variables inside a variable?
+0

In the past I have read about the fact that some programmers use a variable to hold two or more variables (instead holding a mere value or an array).
There might also be cases when programmers use a variable to hold just one other variable.
What could be a good typical simple example for the need in this practice in programming in general? What is a typical problem to solve with this?
