k0ka [10]

Answer:

False.

Explanation:

When we create an array of size n, then it's index will starts from 0 to n-1. Array index starts with 0 because the first element of the array holds the memory location that refers to 0 element away.Similarly 2nd element of array is 1 distance away from that location. That is why index starts with 0 and goes to n-1 if the size  is n.

In the question question, int list[25] is given. So the index will be from 0

to 25-1 only.If index will goes to 25 then it will go beyond the array.
