Question

What is the last legal subscript that can be used with the following array?

int values[5];

A) 0
B) 5
C) 6
D) 4

Answer 1

The last legal subscript for the array 'int values[5];' is 4, because array indices in C start at 0, making the valid indices 0 through 4.

Step-by-step explanation:

The last legal subscript for the array 'int values[5];' is 4. In C, array indices begin at 0, so for an array of size 5, the valid indices range from 0 to 4. Accessing values beyond this range, such as values[5], would exceed the array bounds and may result in undefined behavior. It's crucial to adhere to the correct index range to ensure proper and safe array manipulation. Therefore, to access the last element in the array 'values,' you would use values[4], and attempting to use values[5] would be invalid.
