Answer:
Reference
Explanation:
Variables provide reference to the stored data value.
For example:
int i = 0;
Here i is a variable of type int with an initial value of 0. i is a reference to this stored value 0. Now if I want to update the data, I can do so using this reference.
i = 1;
Now the reference is used to manipulate the stored data and change it to 1. In a similar manner all updates to the value can be done using the variable reference.
