Show Explanation
Before that, we should know that char can store numbers only -128 to 127. The most significant bit is kept for the sign bit. Clearly, 11111111 represents a negative number. To check which number it represents we find the 2’s complement of it, which is 00000001, which is nothing but 1 in decimal.
Hence, 11111111 represents -1, which is the required output.
