  • C 20 ✔ ✖
  • D 0 ✔ ✖
Correct Answer: Option C

Explanation

The declaration:

int x[20];

creates an array that can store 20 elements.

  • The number inside the brackets [20] specifies the total number of elements

  • Array indexing starts from 0

  • Valid indices range from 0 to 19

So even though the last index is 19, the array still contains 20 elements.

Correct Answer: C) 20

Description:
x[20] means the array size is 20, not 19.
