Question

For array "a" is a[ ] a valid way to access an element?

Answer 1

Yes, a[] is a valid way to access an element in an array. The square brackets notation indicates the index position of the element you want to access, starting from 0.

Step-by-step explanation:

Yes, a[] is a valid way to access an element in an array. The square brackets notation is used to indicate the index position of the element you want to access. In most programming languages, array indexing starts at 0, so a[0] refers to the first element in the array, a[1] refers to the second element, and so on.

For example, if you have an array a with elements [5, 8, 12, 3], then a[0] would give you the value 5, a[1] would give you the value 8, and so on.

Using square brackets to access array elements is a fundamental concept in programming and is widely used in various programming languages like C, Java, Python, and more.
