Question

For a value to be potentially used as an index, it must be any numeric type or an expression that evaluates to such.

a) True
b) False

Answer 1

The statement is true. In programming, an index is a numeric value used to access elements in a data structure, such as an array.

Step-by-step explanation:

The statement "For a value to be potentially used as an index, it must be any numeric type or an expression that evaluates to such" is true.

In programming, an index is a value that is used to access elements in an array or other data structure. Generally, indexes are numeric, such as integers, floating-point numbers, or even expressions that evaluate to a numeric value. This allows programmers to access specific elements in a collection by specifying their position using the index value.

For example, in the programming language Python, you can use integers or expressions that evaluate to integers as indexes to access elements in a list. Here's an example:
my_list = [10, 20, 30, 40, 50]

print(my_list[2])
# Output: 30

print(my_list[2+2])
# Output: 50
