Question

Char data types has a range of - 128 to 127. define a char type variable with value 129 and check what the output will be.​

Answer 1

Answer:

-127 is stored as 2's compliment of 127

127 is 01111111 in binary

2's compliment=(1's compliment of a number) + 1

therefore, 2's compliment of 127(01111111) is 10000001(-127).

And 10000001 is 129:: Therefore when you give 129 to a char variable, compiler takes it as negative number 127.
