Consider the following declaration of an array in ‘C’ language:
int A[6] = {1, 2, 3, 5};
Which of the following statements is true?
  • a)
    Both A[2] and 2[A] represent the value 2.
  • b)
    Both A[2] and 2[A] represent the value 3
  • c)
    A[2] is the correct way to access an element of A, but 2[A] will give an error
  • d)
    The last two elements of the array A are 3 and 5
Correct answer is option 'B'. Can you explain this answer?

Consider the following declaration of an array in ‘C’ lang...
Explanation:

Accessing elements in an array:
- In C language, elements in an array are accessed using indices within square brackets.
- The index starts from 0 for the first element in the array.

Given array declaration:
- int A[6] = {1, 2, 3, 5};
- Here, the array A has 6 elements, but only 4 elements are initialized.

Accessing array elements:
- A[2] represents the value at index 2 of array A, which is 3.
- In C language, array name followed by index (e.g., A[2]) is the standard way to access elements.

Understanding 2[A]:
- In C language, the expression 2[A] is equivalent to A[2].
- This is because array subscripting is commutative in C, meaning A[B] is the same as B[A].

Correct statement:
- Therefore, both A[2] and 2[A] represent the value at index 2 of array A, which is 3.
- So, the correct statement is that both A[2] and 2[A] represent the value 3.

Conclusion:
- The correct way to access an element of array A is A[2].
- The value at index 2 of array A is 3, making option 'b' the true statement.
