To answer this question, let's first clarify the difference between indexes and subscripts.
Indexes are commonly used in computer programming to access elements in an array or a list. They are typically represented by integers and start from 0. For example, in an array with elements [1, 2, 3], index 0 refers to the first element (1), index 1 refers to the second element (2), and so on.
On the other hand, subscripts are used in mathematical notation to represent different variables or parameters. They are typically represented by letters or symbols and are used to distinguish between different variables or parameters within a formula or equation. For example, in the equation y = mx + c, the subscripts m and c represent different variables.
Based on these definitions, we can conclude that the statement "Indexes can be used as subscripts while subscripts cannot be used as indexes" is true.
Option A) True - This option is correct because indexes can be used as subscripts in mathematical notation. For example, if we have an array [1, 2, 3] and want to access the element at index 1, we can write it as array[1]. In this case, the index 1 is used as a subscript.
Option B) False - This option is incorrect because subscripts can be used in mathematical notation, but they cannot be used as indexes in computer programming.
The correct answer is A) True.
