C - Variables and Data Types

Aconst int val = 0xGG;

Bconst int val = 255x;

Cconst int val = 0xFF;

Dconst int val = "0xFF";

Step-by-Step Solution

Solution:

Step 1: Understand hexadecimal literals
Hex literals start with 0x followed by digits 0-9 or letters A-F.
Step 2: Check options
const int val = 0xFF; uses valid hex 0xFF (255 decimal). const int val = 0xGG; has invalid hex digits G. const int val = 255x; has invalid suffix. const int val = "0xFF"; uses string instead of int.
Final Answer:
const int val = 0xFF; -> Option C
Quick Check:
Hex literals start with 0x and valid digits [OK]

Quick Trick: Hex literals use 0x prefix and digits 0-9, A-F [OK]
