What is the expected output on a typical 64-bit system?

A8

B4

C2

D16

Step-by-Step Solution

Solution:

Step 1: Understand sizeof operator on 64-bit systems
On most 64-bit systems, long is 8 bytes (64 bits).
Step 2: Match the output of sizeof(long)
The sizeof operator returns the size in bytes, so it returns 8.
Final Answer:
8 -> Option A
Quick Check:
long = 8 bytes on 64-bit [OK]
