Question 1(xi)

A single dimensional array has 50 elements, which of the following is the correct statement to initialize the last element to 100.

  1. x[51]=100
  2. x[48]=100
  3. x[49]=100
  4. x[50]=100
Answer

x[49]=100

Reason — In Java, arrays use zero-based indexing, meaning the first element of the array is at index 0. For an array with n elements, the last element is at index n - 1.
Given a single-dimensional array with 50 elements, the indices range from 0 to 49. Thus, the correct index for the last element is 49.
