Question

(5) Consider the following array declaration
int arr [9]= (11,3,5,2,9,23,56,0,67};
Then which of the following will be true?
(a) arr [4]-2

Answer 1

The provided array declaration has a syntax error. The correct way to initialize elements in an array using curly braces { } should be:
int arr[] = {11, 3, 5, 2, 9, 23, 56, 0, 67};
Given the corrected array initialization:
arr = {11, 3, 5, 2, 9, 23, 56, 0, 67};
To evaluate the expression arr[4]-2, we can find the value of arr[4] and then subtract 2 from it.

arr[4] = 9
9 - 2 = 7

Therefore, the expression arr[4]-2 evaluates to 7.
