Answer:

A.)

arr[0] = 10;

arr[1] = 10;

Explanation:

Given the array:

arr = {1,2,3,4,5}

To set the first two elements of array arr to 10.

Kindly note that ; index numbering if array elements starts from 0

First element of the array has an index of 0

2nd element of the array has an index of 1 and so on.

Array elements can be called one at a time using the array name followed by the index number of the array enclosed in square brackets.

arr[0] = 10 (this assigns a value of 10 to the index value, which replace 1

arr[1] = 10 (assigns a value of 10 to the 2nd value in arr, which replaces 2
