Solution

failed
failed

The answer is the last one: 4.

Explanation for each option:

  • 6: This is incorrect because 6 is the last element in the array.
  • Depends on the compiler: This is incorrect because the value stored in memory is determined by the array's structure and initialization, not by the compiler.
  • 2: This is incorrect because 2 is the second element in the first row of the array.
  • 4: This is correct because the array is stored in row-major order. After the first row \(\{1, 2, 3\}\), the next value in memory is the first element of the second row, which is 4.

Summary: The value stored in memory immediately after the 3 is 4.
