What does changing the value of a tag in the subscript of an array allow you to do?

Changing the value of a tag in the subscript of an array allows you to change the element of the array that logic references. In programming, an array is a collection of elements identified by index or key values. By modifying the subscript, you effectively direct the program to access or manipulate a specific element within that array.

For example, if you have an array of integers and you use a variable as the subscript, changing that variable's value will change which integer the program retrieves or modifies during execution. This functionality is essential in dynamic programming environments where elements in an array need to be accessed or updated based on specific conditions or calculations.

The other options do not accurately describe the effect of changing a subscript value: modifying an array's size typically requires a different approach since most arrays have a fixed size once declared; reinitializing an array usually means setting all elements to a default value, rather than merely changing a reference; and sorting the elements is a process that involves comparing and rearranging multiple items, which is distinct from simply changing a reference to one element in the array.
