What is the value assigned as index to the first element in a list?Select one:a.0b.1c.None of themd.-1

1. Break Down the Problem

The problem is asking for the index of the first element in a list.

2. Relevant Concepts

In programming languages such as Python, Java, and C, lists (or arrays) typically use zero-based indexing. This means that the index of the first element in the list is 0.

3. Analysis and Detail

• Option a: 0 - According to zero-based indexing, this is correct as the first element is at index 0.
• Option b: 1 - This option would be true in one-based indexed languages, but it is not the case for most common programming languages.
• Option c: None of them - This is incorrect, as one of the options does provide a valid index.
• Option d: -1 - This is not correct for indicating the first element; in some languages, -1 is used to indicate that an element does not exist within a list.

4. Verify and Summarize

The correct index for the first element in a typical list structure is indeed 0. Hence, the answer aligns with common programming standards.

Final Answer

The value assigned as index to the first element in a list is a. 0.
