Answer: a) 0, 1, 2, 3.
Explanation:
In most programming languages, including popular ones like Python, Java, C++, and JavaScript, array indexing typically starts at 0. This means the first element of an array is accessed using index 0, the second element with index 1, and so on.
For example, in Java, accessing the first element of an array called 'arr' would be done by using arr[0]. Accessing the second element would be done by using arr[1], and so on.
An array's index numbering begins at 0, which is the zero-based indexing method used in many programming languages for arrays. option A
An array's index, also known as a subscript, typically begins at 0. This means that the first element in an array is accessed with index 0, the second with index 1, and so on. This indexing method is considered zero-based indexing. In languages like C, Java, and Python, among others, arrays start at 0, making the correct sequence 0, 1, 2, 3, and so forth, as mentioned in choice (a).
Abstract index notation, which includes systems such as the Einstein summation convention, operates differently and is used in more advanced mathematical contexts, such as representing tensor components in physics. Here, the use of indexes depends on the context and the specific type of notation being used. However, when referring to the numbering of simple data structures like arrays, it's the zero-based indexing that's most pertinent.
