What is the range of the char type?

the answer is B.

the range of char is 1 Byte.

i.e 16 bits.

so the range will be 0 to 2^16-1

ans is 2 to the power 16 which is 65535 because char does not use msb as a sign bit. its uses all 16 bits for storing values

0 to 2¹⁵-1

the range of char is 0 to 2^16 -1 reffer (http://java.sun.com/docs/books/tutorial/java/nutsandbolts/datatypes.html)
char range is 65535 that is equivalent to 2^16 -1 so answer c is right

sorry answer d is correct

the range of char is 0 to 2^16 -1
http://java.sun.com/docs/books/tutorial/java/nutsandbolts/datatypes.html) char range is 65535 that is equivalent to 2^16 -1 so answer B is right

0 to 2^15-1
