1. 99

Explanation:

As the array is declared with space of 100 integers, 100 integers' space will be allocated to variable num. Moreover, Index number of last component is always the length - 1 because array's index start with 0 and ends till length-1. As array will initialize all the remaining spaces with garbage value so they will be displayed if accessed through num[index] where index s the index number to be displayed.

As size of array is 100. So, 99 will be the index of the last component of the array.
